Borosilicate glass: the material that won't let you down

Resistant to a thermal shock of up to 500 °C, this type of glass is not the same as your everyday water glass. Borosilicate glass is the same material used in laboratories and medical equipment—in other words, it’s no joke when it comes to durability. Its composition includes boron oxide, which gives it exceptional rigidity, a perfectly smooth surface, and total chemical inertness. In concrete terms: it doesn't react to anything, absorbs no bacteria, no lubricant, and no odor. It remains exactly as it is, session after session, year after year. For intimate toys, that is a rare and precious quality. Your pleasure deserves a material as reliable as you are—and honestly, that’s the bare minimum.

Why borosilicate glass is a game-changer for your pleasure

Choosing a toy made of this material means choosing uncompromising safety. Its non-porous surface prevents any bacterial growth, making it hygienically impeccable—a quick wash with warm water and you're done. Then there is the tangible sensory pleasure: the density of the glass offers unique internal pressure that is impossible to replicate with silicone or plastic. And because it conducts temperature, you can use it cold or warm to explore new sensations alone or with a partner. Finally, it’s an investment that lasts: no wear, no discoloration, and no degradation of the material over time. You buy it once, you enjoy it for a long time.

This is one of its biggest advantages: maintenance is super simple. Warm water and mild soap are enough for regular cleaning. You can also put it in the dishwasher or sterilize it in boiling water. It is compatible with all types of lubricants—including oil-based ones—without ever damaging the surface. Honestly, it is one of the most low-maintenance materials there is.

Can you really put it in the fridge or in hot water?

Yes, and that is precisely where this material becomes interesting. A few minutes in the fridge or in warm water are enough to completely change the sensation.
