These huge anal balls are internally weighted, with a silicone skin and convenient retrieval cord. The steel balls inside provide weight and resistance, while the silicone provides a smooth feel and easily sterilized exterior. The easy retrieval cord has a finger loop, also made of premium silicone. The entire outside is phthalate-free and perfect for anal play. Clean after use with mild soap or toy cleaner. Do not use with silicone lubricants only water based.
