Glass sex toys are intimate pleasure devices made from borosilicate glass (Pyrex), a durable, body-safe material that is non-porous and hypoallergenic. These toys come in various shapes and textures, including dildos, anal plugs, and massagers, offering a smooth and firm sensation. Unlike silicone or jelly toys, glass toys provide a unique, weighty feel that enhances stimulation. They can be used for temperature play, as they retain heat or cold when exposed to warm or chilled water. Their rigidity also allows for precise pressure, making them great for G-spot or prostate stimulation.
