An object of beauty lives on forever, and a glass dildo can last a lifetime! Hard, smooth, seamless hand blown works of art, glass dildos will both excite and arouse the most discriminating adult. Glass absorbs temperatures… warm in your hand or run under cold water to create different sensations. Glass toys are made from medical grade non-porous hypoallergenic glass. This is the same durable glass used in Pyrex and contains a scientific grade borosilicate that resists breakage.
