Good to know — porosity, safety & the honest detail
Is glass body-safe?
Yes. Toy-grade glass is tempered borosilicate — non-porous, compatible with every lube, and it doesn’t absorb anything, so it cleans completely. It’s one of the safest, most hygienic materials there is.
Can a glass toy break?
Quality borosilicate is strong and handles temperature well, but it’s still glass: inspect it for chips or cracks before each use, retire it if you find any, and avoid dropping it on hard surfaces.
How do you do temperature play safely?
Warm it in a bowl of warm water, or cool it in the fridge (never the freezer). Skip boiling-hot or icy extremes, and always test the temperature on your wrist first.

How to care for Glass
