OO20 vs OO30: How to Choose the Right Squishy Stimtoy Firmness

Quick Answer

If you want maximum squish and a melt-in-your-hand feel, go with OO20 super soft. If you want a bit more structure and resilience while keeping it soft, OO30 is your pick. Use our decision rules below to match the firmness to your sensory needs and intended use.

Choosing between OO20 and OO30 silicone can feel tricky when you're staring at product pages. Both are soft and squishy, but the difference in firmness changes the experience significantly. This guide gives you concrete decision rules and trade-offs so you can pick the right squishy stimtoy firmness without guesswork.

Tentickle uses these two shore ratings for its squishy stimtoys, and each has a distinct personality. Your choice depends on whether you prioritize ultra-softness or durability, and how you plan to use the toy.

What Does OO20 vs OO30 Actually Mean?

The 'OO' scale measures the firmness of very soft silicones. Lower numbers mean softer, squishier material. OO20 is what Tentickle calls super soft—it yields easily and feels almost marshmallow-like. OO30 is soft but slightly more resistant, giving it a bit more body. To get a hands-on feel, Tentickle offers a silicone sample pack that includes both, along with OO50 and 10A firmness options. That's your safest bet if you're new to platinum silicone.

Neither is right or wrong; they serve different moods and uses. Knowing the difference helps you avoid disappointment, whether you're buying for fidgeting, sensory play, or as a collectible.

• OO20 = super soft, extremely squishy, delicate
• OO30 = soft but with more structure, slightly more durable
• Sample pack includes both for a hands-on compare

Premium-Quality Platinum Silicone: Safe and Body-Friendly

Both OO20 and OO30 squishy stimtoys are made from 100% platinum silicone. That means they're non-porous, hypoallergenic, and free from phthalates and other nasties. You can clean them easily and they won't harbor bacteria. This quality is a big reason why they cost more than mass-produced jelly toys—but the feel and safety are worth it.

Platinum silicone also has a lovely skin-like texture that makes these stimtoys pleasant to hold for long periods. Whether you squeeze them during a stressful meeting or use them as a fidget, the material feels great in hand.

• Platinum silicone is non-porous and safe
• Easy to clean with soap and water
• Long-lasting if stored properly

How to Use Your Squishy Stimtoy Safely and Effectively

Squishy stimtoys are not designed for internal use—they're for squeezing, fidgeting, and sensory satisfaction. If you want a soft toy for internal play, you'll need a different product. But for hand stimulation, they're perfect. Keep in mind that OO20 super soft is more fragile, so avoid aggressive pinching or twisting that could tear it.

For longer sessions, choose OO30 if you want a toy that holds its shape. For a quick squeeze or a decorative desk buddy, OO20's extra squish is delightful. Always store your squishy away from direct sunlight and sharp objects to keep it in top condition.

• Not for internal use—keep it as a hand toy
• OO30 handles frequent handling better
• Store away from heat and sharp objects

Decision Rules for Choosing Firmness

• Rule 1: Choose OO20 if you want maximum squish: If you love a toy that yields completely under pressure and feels almost liquid, OO20 is your match. It's the most satisfying for stress squeezing and gentle kneading. Best for sensory seekers who prioritize softness over durability.
• Rule 2: Choose OO30 if you want a bit more structure: If you plan to handle the toy frequently or want it to keep its shape better, OO30 offers a firmer yet still soft feel. It's also a better choice for toys with fine details, like the nubbins on Nemonee. Good for everyday fidgeting and toys with intricate textures.
• Rule 3: When in doubt, try a sample pack: Tentickle's silicone sample pack includes OO20 and OO30 (plus OO50 and 10A) so you can feel the difference before committing. This is the smartest way to avoid guesswork. The sample pack is a low-cost way to discover your preference.

Two Real Squishies Compared

• Burgore 'Trophy' #2 squishy stimtoy super soft (OO20): Firmness: Super soft (OO20). Size: 5cm x 6.5cm. Not for internal use; meant as a stimtoy or novelty item. If you're drawn to the ultra-squishy side, this burger buddy shows what OO20 feels like. Its small size makes it great for desk fidgeting.
• Nemonee 'Trick Or Treat' #1 soft (OO30) GITD: Firmness: Soft (OO30). It's a vibe sleeve that glows in the dark, with a circle of nubbins that transfer vibrations well. This proves OO30 still feels soft and malleable—but it can hold a bit more shape, which is why it works as a sleeve rather than just a squishy.

Who Should Choose Which Firmness?

Best for

• OO20 is best for those who love an ultra-soft, squishy feel and use toys mainly for gentle fidgeting or sensory play.
• OO30 is best for those who want a soft toy that's still resilient enough for regular handling and detailed textures.

Not for

• If you prefer a firmer, more substantial toy for deeper pressure, consider a higher shore rating like OO50 or 10A instead of OO20 or OO30.

Choosing between OO20 and OO30 comes down to how you like your squish: maximum melt or a little more body. Use these decision rules and, if you're still unsure, the sample pack takes the guesswork out. Either way, you're getting premium platinum silicone that feels great in hand.
