Glass: This safe and sexy toy is made from one solid piece of glass. Glass sex toys are smooth and friction-less, and warm to body heat. Glass is also non-porous, (so it will not absorb anything) and is compatible with all types of lubricant. Some glass toys can be sterilized by boiling and put in the dishwasher safe, but please consult manufacturers' care instructions prior to boiling. All glass toys are ensured to be free of cracks or sharp edges prior to shipping - but please inspect your toy prior to use. If the toy is dropped, please check for chips before using.
