SoftSkins is a porous material that is often used to make various types of sex toys such as dildos and vibrators. Its main components include several variations of thermal plastic elastomer (TPE), silicone, and a mixture of polyvinyl chloride. It is manufactured to closely resemble real human skin. Because of its exceptionally high molecular density, this material is extremely flexible. However, it can be hard to clean since the porous surface harbors bacteria.
