SquarePeg Toys Review: The Squishiest Silicone in the Game (And Why That Matters)

The SuperSoft silicone

SuperSoft silicone is SquarePeg's entire identity, and for good reason. Standard platinum-cured silicone from brands like Mr Hankey's or Tantus comes in firmness levels ranging from slightly yielding to rock-hard. Even the softest options from those brands maintain their shape under pressure. You push, the silicone pushes back.

SquarePeg's SuperSoft doesn't push back. It collapses, compresses, folds in on itself. You can squeeze an Egg Plug down to half its resting diameter with one hand. During insertion, the material deforms around your anatomy rather than demanding your anatomy accommodate it. The practical result: toys that measure intimidating on paper feel manageable in practice. A 3-inch diameter Egg Plug in SuperSoft might only require the same relaxation as a 2-inch plug in standard silicone, because the material does half the work for you.

This isn't a gimmick. The pelvic floor muscles and anal sphincter respond differently to yielding pressure versus rigid pressure. A firm object demands active relaxation from the muscle to allow passage. A soft object reduces the force required because it deforms before the muscle does. For people working on size progression, this is the difference between a frustrating plateau and a gradual, comfortable advance. The muscle still stretches. The experience just doesn't hurt.

The tradeoff is real, though. SuperSoft silicone provides almost zero internal pressure once inserted. If you want that feeling of firm fullness from a plug, where the material actively presses against your walls, SuperSoft won't deliver it. It's there, you know it's there, but it's more of a gentle presence than an insistent one. Some people find this perfect for extended wear. Others find it underwhelming after the insertion is over.

The material also has a distinctive feel in your hands. Where standard silicone feels like, well, silicone, SuperSoft feels closer to a stress ball or memory foam. It's weirdly satisfying to handle. Daniel picked up the Egg Plug off my desk, spent five minutes squishing it, and said 'I don't even use this and I want one.' The tactile quality alone sets it apart from every other toy material I've encountered.

The Egg Plug

The Egg Plug is SquarePeg's signature product and the reason most people discover the brand. It's an egg-shaped plug (shocking, I know) available in sizes from small to XXL, all in SuperSoft silicone. The design is so simple it seems like it shouldn't be special. It's an egg. On a stem. With a base.

But the egg shape combined with SuperSoft silicone creates something no traditional plug can replicate. The widest point compresses during insertion, requiring far less relaxation than a rigid plug of the same diameter. Once past the sphincter, the egg settles into place and the SuperSoft material conforms to your internal anatomy rather than holding a fixed shape. It's like the difference between sitting on a wooden chair and sitting on a bean bag. Both support you. One adapts to you.

I wore the medium Egg Plug for an entire workday. Eight hours, sitting at a desk, walking to get coffee, standing in line at the post office. Forgot it was there twice. That's never happened with a standard firmness plug, where I'm always aware of the rigid shape pressing against my body from the inside. The SuperSoft egg just... exists. Quietly. Comfortably. The narrow stem between the egg and the base means your sphincter closes around almost nothing, which eliminates that constant stretch sensation that makes other plugs fatiguing over hours.

The base is thin and flexible, following the same SuperSoft philosophy. It tucks between your cheeks without creating a visible ridge under clothing and doesn't dig into your skin when you sit. b-Vibe's Snug Plugs have a similarly well-designed base for extended wear, but those are weighted and firm, which is a different experience entirely. The Egg Plug is about disappearing, the Snug Plug is about being constantly felt.

“I wore this to the post office. Nobody knew. I barely knew. That's the whole point of the Egg Plug.”

Sizing on the Egg Plug deserves attention. The small starts at about 1.5 inches max diameter, which is a true beginner size. The XXL tops out over 4 inches, which is not. Because SuperSoft compresses so much, people sometimes jump sizes too aggressively, thinking 'well it's soft, so the next size up should be fine.' Your body still needs time to adapt. The softness of the material doesn't eliminate the need for patience; it just makes each step more comfortable. If you're new to anal play, our beginner anal guide covers the progression principles that apply regardless of what material you're working with.

Slink series (depth play)

Depth play is a niche within a niche, and SquarePeg's Slink series is the gold standard for it. Slinks are long, flexible, tapered tubes of SuperSoft silicone designed to travel deep into the colon. Lengths range from 12 inches to over 24 inches. If that makes you clench, that's a reasonable response. But for the people who are into this, there is nothing else that works as well.

Rigid depth toys exist, and they're terrifying for good reason. The colon curves. It bends. It does not appreciate a stiff rod trying to negotiate those turns at speed. SuperSoft silicone follows the curves because it has no structural rigidity of its own. The toy bends where your body bends. It doesn't force a path; it takes the path your anatomy offers. This is why the depth play community adopted SquarePeg almost universally. The material was specifically designed for this purpose.

I tried the Slink Small (14 inches) after extensive warm-up and a healthy amount of water-based lube. The initial insertion feels like any soft plug. Past six or seven inches, you enter territory where the colon starts curving, and here's where SuperSoft earns its reputation. The toy bent with me. No pressure points. No resistance against the walls. Just a smooth, continuous sensation of depth that felt intense in a way that's hard to compare to anything else. I stopped at about ten inches, which was my comfort boundary, but the toy had four more inches of runway if I'd wanted it.

The diameter options matter more for Slinks than for plugs. Thinner Slinks follow curves more easily but provide less sensation. Thicker Slinks fill more but require more relaxation at each bend. Most people in the depth play community recommend starting with the thinnest diameter available and sizing up only after you're comfortable with the full length at a smaller girth.

One practical complaint: Slinks in SuperSoft are floppy. Very floppy. Holding one feels like holding a silicone noodle. This makes insertion past the first few inches a two-handed operation, or you need a partner helping. The toy won't push itself forward; you're guiding it the entire time. For solo depth play, some people prefer the slightly firmer versions that SquarePeg occasionally offers, which maintain enough structure to feed in with one hand. Check availability, because the firm Slinks aren't always in stock.

Leo series

Not everything SquarePeg makes is for the advanced crowd. The Leo is their most conventional product: dildo-shaped, shaft-and-head proportions, available in SuperSoft and sometimes in a slightly firmer formulation. These are the toys you'd recommend to someone who wants to experience the SuperSoft material without jumping straight into egg plugs or depth play.

The shape is uncircumcised realistic with a defined head and gentle texture along the shaft. Nothing extreme. Nothing weird. Just a well-proportioned dildo in a material that feels unlike any other dildo you've handled. In SuperSoft, the Leo compresses during penetration, creating a sensation that's softer and more forgiving than standard silicone but still provides enough shape to feel present. It's the middle ground between 'is anything even in there?' and 'oh god that's firm.'

I found it most useful for vaginal use, where the SuperSoft material has a different advantage than it does anally. Vaginally, the softness means the toy conforms around the G-spot area rather than pressing a fixed shape against it. Some people prefer that conforming sensation to a rigid toy that hits one specific spot. Others find it too diffuse and want something with more backbone. Vixen Creations' VixSkin line handles this better with their dual-density approach: soft exterior, firm core. The Leo is soft all the way through.

For anal use, the Leo works but doesn't outperform the Egg Plug for plugging or the Slink for depth. It sits in a tweener zone where it's a decent dildo in a unique material but not the best at any specific anal application. If you're buying one SquarePeg product and you're interested in anal, get the Egg Plug. If you want a soft dildo for vaginal use or you're curious about the SuperSoft feel without committing to a specialized shape, the Leo is the right entry point.

Sizes run from small (about 5.5 inches insertable) through extra-large. The small and medium sell best, which makes sense: at those sizes, SuperSoft is a texture novelty. At the larger sizes, SuperSoft becomes a practical tool for making ambitious dimensions achievable. The right size depends entirely on what you're after.

Size progression

SquarePeg's product range is built around progression, and it's one of the most thoughtful size ladders in the industry. Within the Egg Plug line alone, you can go from a small that's appropriate for near-beginners to an XXL that's firmly in advanced territory, all in the same shape and material. That consistency matters. When you size up and the only variable that changes is diameter, you can isolate exactly how much more your body is handling without confounding factors like different shapes, firmness levels, or materials.

The progression philosophy extends across product lines too. Someone might start with a small Egg Plug for basic anal comfort, graduate to a medium, then branch into the Slink series for depth exploration while continuing to size up with the Egg Plugs for girth. Two different dimensions of development, both supported by the same SuperSoft material that makes each step less daunting than it would be with standard silicone.

What SquarePeg doesn't do well is the very beginning of the journey. Their smallest Egg Plug, while modest by SquarePeg standards, is still a step above what a true beginner with zero anal experience should start with. For someone who has never inserted anything anally, a b-Vibe Snug Plug 1 or a slim silicone plug from Tantus is the safer first step. SquarePeg's lineup picks up where those introductory products leave off. Think of it as the intermediate-to-advanced toolkit rather than the starter kit.

The community around SquarePeg is smaller than Bad Dragon's but remarkably helpful. Reddit threads on size progression with SuperSoft products include timelines, personal experiences, and specific size-up advice that you won't find on the company's website. If you're serious about progression, spend an hour reading community experiences before ordering. The collective wisdom is worth more than any product description.

Care & maintenance

Platinum-cured silicone care applies universally here. Nonporous surface means soap and warm water handles daily cleaning. For full sterilization between partners or between anal and vaginal use, boiling for 3-5 minutes eliminates everything. Top rack of a dishwasher works too (no soap, no other dishes). A 10% bleach solution followed by thorough rinsing is the nuclear option for the truly cautious.

SuperSoft silicone has one care consideration that standard silicone doesn't: deformation during storage. Because the material is so yielding, leaving a SuperSoft toy under weight or pressed against a surface for extended periods can cause temporary (sometimes semi-permanent) warping. An Egg Plug stored on its side with a heavy book on top will flatten slightly on that side over weeks. Store upright when possible, or in a bag with nothing pressing against it. The warping isn't structural damage and usually corrects itself over a few days at room temperature, but it's annoying.

Lint is the same problem you get with any matte silicone, amplified by the softness. SuperSoft's surface has more micro-texture than standard silicone, giving dust and fibers extra grip. A quick rinse before use becomes habit fast. Storage in individual cloth or satin bags prevents the worst of it. Do not store SuperSoft toys touching each other or touching other silicone products; the surface chemistry between silicone items in prolonged contact can cause a reaction that degrades both surfaces.

Lube compatibility is standard: water-based only. Silicone lube bonds with silicone toys at a molecular level and will destroy the surface over time. This is especially important with SuperSoft because the material's micro-texture means damage shows faster and affects the feel more dramatically than it would on smooth, firm silicone. One session with silicone lube probably won't ruin the toy. Repeated exposure absolutely will. Just use water-based. The extra reapplication is a minor inconvenience compared to replacing a $60 plug.

vs. the competition

SquarePeg vs. b-Vibe is the comparison that comes up most for anal-focused buyers, and the answer is simple: they serve different purposes. b-Vibe makes the best vibrating and weighted plugs on the market, with education resources that hold beginners' hands through the entire learning curve. SquarePeg makes the best ultra-soft silicone for size progression and extended wear. If you want vibration, buy b-Vibe. If you want the softest material available, buy SquarePeg. There's almost no overlap. Many serious anal enthusiasts own products from both.

SquarePeg vs. Mr Hankey's is a material philosophy debate. Mr Hankey's platinum silicone is denser, more detailed, and available in multiple firmness levels from yielding to rock-solid. Their customization options crush SquarePeg's limited lineup. But Mr Hankey's softest firmness isn't even close to SuperSoft. If you've hit a size plateau with standard silicone and need a material that gives more, SquarePeg is the only answer. If you want the highest quality, most detailed dildo in a firmness that still has structure, Mr Hankey's wins.

Bad Dragon offers a soft firmness option that some people compare to SuperSoft. Having handled both, they're not equivalent. Bad Dragon's soft is yielding but still maintains its shape under gravity. SquarePeg's SuperSoft flattens under its own weight. The difference is significant in practice: Bad Dragon soft compresses maybe 20-30% during insertion, while SuperSoft compresses 40-50% or more. For pure softness, SquarePeg is in a class by itself. For fantasy designs, color options, and community, Bad Dragon wins easily.

Tantus doesn't really compete in the same space. Tantus makes excellent body-safe silicone at budget prices, but their firmness range tops out at 'slightly soft.' If you just want a reliable, affordable plug or dildo in proven platinum silicone, Tantus is the practical choice. SquarePeg is for people who have a specific material requirement that standard silicone can't meet.

“SuperSoft isn't better or worse than standard silicone. Comparing them is like comparing a hammer to a pillow. Both useful, wildly different applications.”

— Sasha, on material philosophy

The honest positioning: SquarePeg is a specialist. They do one thing (ultra-soft platinum silicone) better than anyone on the planet. If that thing is what you need, there's no alternative. If it's not, broader-catalog brands like b-Vibe or Mr Hankey's will serve you better.

Website & ordering

The SquarePeg website looks like it was built during the Obama administration and hasn't been touched since. It functions. Products load. The cart works. But the design is dated, navigation is clunky, and the photography ranges from adequate to 'did you take this with a flip phone?'

Product descriptions are informative but dense. They explain the SuperSoft material well for first-time buyers, include accurate measurements, and provide honest sizing guidance. Credit where it's due: the content is useful even if the presentation is ugly. Some brands have gorgeous websites with zero substance. SquarePeg has the opposite problem.

Ordering is painless compared to the circus at Bad Dragon. No drops. No limited windows. No bots competing for inventory. You browse, you select, you buy. Stock levels vary and popular sizes sell out, but the restocking cadence is reasonable and they don't manufacture artificial scarcity. Shipping is from the US, standard packaging, no branding on the box. Delivery times run about a week domestically.

The biggest website gripe: no reviews or ratings system. You can't read other customers' experiences on the product pages. This pushes buyers to Reddit and forums for real user feedback, which actually provides better information than curated on-site reviews anyway, but it's a gap in the buying experience that most modern shops have filled. When you're spending $60-100 on a toy in an unusual material, reading that twelve other people found the medium perfect for extended wear is reassuring. SquarePeg forces you to seek that reassurance elsewhere.

Pricing & value

SquarePeg surprised me by costing less than I expected. Egg Plugs start around $29 for the small and climb past $150 for the largest sizes. Slinks run from about $69 to several hundred depending on length and diameter. Leo dildos sit in the mid range. For handmade platinum-cured silicone from an American workshop, these prices are competitive.

Compare that to the competition. A b-Vibe Snug Plug runs $40-60 for a non-vibrating silicone plug. A Mr Hankey's dildo starts at $125. A Bad Dragon medium dildo hits $85-130 before add-ons. SquarePeg's pricing lands in the lower half of the premium silicone market while offering a material that nobody else makes. The value math works out better than most competitors in this category.

Where it gets tricky is the lack of bundles or progression sets. b-Vibe sells the Snug Plug system as a set with a discount. SquarePeg sells each size individually at full price. Building a three-size Egg Plug progression (small, medium, large) runs about $150-180 total. Not unreasonable for three platinum silicone products, but a bundled option at a slight discount would move more product and serve customers better. Seems like an obvious gap in their sales strategy.

“Three platinum silicone plugs for the price of one Mr Hankey's custom pour. The value math is friendlier than you'd expect from a specialist brand.”

— Sasha, on pricing

The durability argument applies here too. Platinum-cured silicone doesn't degrade. A $40 Egg Plug that lasts indefinitely costs less per year than the cheap TPE plugs people replace every few months when they start smelling weird or developing that sticky film. Body-safe materials cost more upfront and less over time. SquarePeg's prices make that calculus easier than most premium brands.
