Body-Safe Sex Toy Materials 101: Silicone vs Glass
By Zoey Unicorn · 7 min read
If I could get every single customer to read one article before they ever buy a toy, it would be this one. Material is the thing that decides whether a toy is safe to put inside your body, and it is the thing the cheapest sellers hope you never ask about. So let me walk you through it the way I would if you were standing in my shop.
The headline is simple. You want nonporous, body-safe materials, and you want to avoid porous mystery materials. Once you understand why, you will shop smarter forever.
Why materials matter
Your genital tissue is some of the most absorbent tissue on your body. Whatever a toy is made of, your body is in close contact with it, sometimes internally, sometimes for a while. So the material is not a detail. It is the whole safety question.
Good materials are nonporous, which means they do not have microscopic holes where bacteria, fluids, and grime can hide. That makes them genuinely cleanable. Bad materials are porous, which means they trap that stuff no matter how hard you scrub, and that is how toys start to smell, degrade, and harbor bacteria.
Silicone done right
High-quality silicone is my desert-island material. It is nonporous, body-safe, warms to your body temperature, comes in soft and firm versions, and lasts for years if you treat it well. When people say a toy feels premium, it is usually good silicone they are reacting to.
The catch is that the word silicone gets slapped on labels loosely. Real, full-silicone toys from reputable brands are worth it. Blends and toys that say silicone but feel suspiciously cheap are a gamble. Buy from sellers who are transparent about materials, which, not to be biased, is exactly how we run things here.
Body-safe silicone
Glass and stainless steel
Glass and steel surprise people, but they are some of the safest materials out there. Body-safe glass toys are made from sturdy borosilicate, the same family as kitchenware that handles temperature changes. They are completely nonporous, easy to clean, compatible with every kind of lube, and they hold temperature beautifully if you want to warm or cool them for sensation.
Steel is similar: heavy, smooth, indestructible, and wonderful for firm pressure and temperature play. Both glass and steel last basically forever, which makes them a smart long-term buy even if the upfront price is higher.

What porous means and why to avoid it
Here are the materials to be cautious about: jelly, PVC, TPR and TPE, and anything with a strong chemical smell. These are porous. They cannot be fully sanitized, they can break down over time, and some contain softeners that genuinely do not belong against your body.
If you already own toys like this, you do not need to panic, but you should always use a condom over them and replace them when they start to smell or feel sticky. For anything internal, I would steer you toward nonporous from the start.
Matching lube to material
This part trips people up. Water-based lube is the safe default for everything. It works with silicone, glass, and steel, and it will never damage a toy. Silicone lube feels lovely and lasts longer, but it can degrade silicone toys, so keep silicone lube for glass, steel, or skin only. A hybrid splits the difference for a little extra cushion. When in doubt, reach for water-based and you will never ruin a toy by accident.
Compatible lube
Buy nonporous, clean it properly, match your lube, and you have got toys that stay safe and last for years. That is the whole game.
