One of the reasons why glass dildos are becoming so popular is because smooth glass plus smooth penetration equals almighty pleasure.

Even twisted or curved glass dildos with ridges or bumps are smoother than most plastic or silicone dildos. When a little lubricant (water-based or silicone) is added to the smooth surface of glass, it becomes even more slick, making for some great fun!

The majority of glass dildos are made from high-grade borosilicate glass, which is a durable, safe and sturdy material that is used in Pyrex jugs and oven dishes. It can be heated up in warm water or cooled down in your fridge or freezer for intense variations in temperature.
