If you've been shopping for a dildo, plug, or wand-style toy, you've probably noticed the same two materials popping up again and again: medical-grade silicone and borosilicate glass. Both are body-safe, both are non-porous, and both can last for years — but they feel completely different in use, and one will almost always suit you better than the other. This guide breaks down the real-world differences so you can choose with confidence.
The quick verdict
Silicone is the all-rounder. It's warm, flexible, lightweight, and forgiving — the default recommendation for most beginners and anyone who wants a versatile toy that's easy to live with. Glass is the specialist. It's rigid, weighty, beautifully smooth, and uniquely suited to firm pressure and temperature play. Neither is "better" in the abstract; the right answer depends on what sensation you're chasing and how you like your toys to behave.
What glass toys actually feel like
High-quality glass toys are made from borosilicate — the same heat- and shock-resistant glass used in lab equipment. They are heavier than they look, completely rigid, and so smooth that they often need less lubricant than other materials. That smoothness is the headline feature: glass glides in a way silicone simply can't replicate.
Because glass has thermal mass, it holds temperature. Run it under warm water for thirty seconds and it stays warm for several minutes. Chill it in a glass of ice water and it delivers a crisp, focused cool sensation. People who love firm internal pressure — whether for G-spot or prostate stimulation — tend to gravitate to glass because the rigidity lets you target a single spot precisely.

What silicone toys actually feel like
Medical-grade silicone is soft, slightly squishy, and skin-warm within a minute of use. It absorbs body heat instead of holding cold, so it always feels welcoming. The flex matters too: a silicone shaft has a little give, which makes insertion gentler and reduces the chance of an uncomfortable bump if you shift positions.
Silicone also takes shape extremely well. That's why almost every contoured G-spot curve, ridged plug, and ergonomic wand handle on the market is silicone — the material lets designers sculpt detail that glass can't match. If you want a toy that adapts to your body rather than the other way around, start with our silicone collection.
Side-by-side: how they compare
Temperature play. Glass wins decisively. Warm or chilled glass produces sensations no silicone toy can match. Silicone warms to body temperature and stays there — comfortable, but one-note.
Weight and rigidity. Glass is heavy and firm; silicone is light and flexible. If you want pressure without effort, glass does the work for you. If you want a toy that bends with you during partnered play or longer sessions, silicone is easier on the wrist.
Glide and lube use. Glass is the slickest material on the market and sips lube. Silicone has more drag and needs a steady reapplication of water-based lube. Important: never use silicone lube on silicone toys — it can degrade the surface. (Glass is compatible with every lube type.) For a full breakdown, see our guide on choosing the right lube.
Cleaning and care. Both are non-porous, which means bacteria can't soak in. Silicone can go in the top rack of the dishwasher or be boiled for three minutes. Glass can be washed with soap and water or wiped with isopropyl alcohol. Detailed steps live in our cleaning and storage guide.
Durability. Properly cared for, both can last a decade or more. Silicone can tear if cut with a sharp object; glass can crack if dropped on tile. Inspect both before each use — any chip, crack, or surface damage means retire the toy.
How to choose, based on what you actually want
If you're brand new to toys: start with silicone. It's forgiving, the learning curve is shorter, and the flex makes mistakes feel like nothing.
If you want firm G-spot or P-spot pressure: glass. The combination of weight and rigidity lets you apply consistent, targeted stimulation without having to push hard yourself.
If you're curious about temperature play: glass, every time. There is no silicone workaround for the sensation of warmed or chilled glass.
If you're shopping for partnered or anal play: silicone for anything thrust-heavy or worn on the body; glass for slower, deliberate, sensation-focused sessions. If anal play is new to you, our step-by-step plug guide is a good first stop, and our anal training kits are silicone-based by design.
If you travel often: silicone wins on weight and TSA-friendliness. Glass is fine to fly with but adds bulk to a bag and needs padded protection.
The body-safe shopping checklist
Material claims aren't always honest, so look for these signals before you buy. With silicone, the listing should specify "100% medical-grade silicone" or "platinum-cured silicone" — anything labeled "silicone blend," "silicone-coated," or simply "soft material" usually contains porous fillers that can harbor bacteria. With glass, the listing should specify "borosilicate" or "Pyrex-style"; ordinary soda-lime glass isn't strong enough to be safe for internal use. Every toy we carry meets these standards, and our team only stocks brands that publish their material certifications.
Discreet shipping is standard on every order, with no store branding on the outside of the package.
Frequently asked questions
Is glass safe to use internally? Yes, when it's borosilicate. That grade is shatter-resistant and rated for repeated thermal shock. Avoid any glass toy that doesn't specify the material, and replace any toy that shows visible damage.
Can I use silicone lube with a silicone toy? No. Silicone-on-silicone can dull or pit the toy's surface over time. Stick with water-based lube for silicone toys. Glass is compatible with every lube type.
How do I warm or cool a glass toy safely? Submerge it in a bowl of warm (not hot) tap water or ice water for about thirty to sixty seconds. Never use a microwave, a kettle, boiling water, or a freezer — sudden temperature jumps can stress even borosilicate. Test against your inner wrist before use.
Which material is easier to clean? Both are equally easy on a day-to-day basis — warm water and a mild, fragrance-free soap is enough for either. Silicone has the slight edge for deep cleans because it can be boiled or run through the dishwasher.
Do glass toys really last forever? They can. There are no mechanical parts to fail and no porous surface to break down. The two things that retire a glass toy are visible damage (chips, cracks, surface scratches) and changing taste — some people just prefer the feel of silicone after a while, which is fine.
