Silicone: Made of 100% silicone, this toy is hypo-allergenic, non-porous (so it won't absorb anything), cleans easily, conducts vibration well and warms to the body. Its high quality construction ensures little to no wear and tear and for vibrating toys, a longer life span. Wash with soap and water. Toys without internal vibrators or with vibrators that can be removed can be sterilized by boiling in a pot of water for 3-4 minutes. When practicing safer sex with a partner, either use a condom or boil in-between uses.
