We had a community member email me about this product, asking about its material. The other version of this toy was listed as rubber, and this was listed as silicone...and of course, the packaging isn't clear, so we went, dug in deep, and did some research.The answer: it is a silicone composite. It does contain both silicone and rubber, but it bills itself as better than ordinary rubber. Of course, since it's not 100% medical grade silicone, you can't boil it or dishwash it (ie, you can't sterilize it, so this should be a personal toy, not one to be shared), but it still looks like a lot of fun for anyone who likes the beadage in the butt -Essin' Em less
