A. The skin of our sex dolls is very close to that of human skin. There are currently two sex dolls made of TPE (Thermoplastic elastomers) and silicone. They are very soft and elastic. Silicone and TPE are both high quality sex materials.  Silicone is typically regarded as the more durable material and TPE as the most realistic.  Here are the main attributes of each material. Silicone A bit harder than TPE but also more durable. More expensive. Easier to clean. Safe for human contact. TPE TPE is softer to the touch. More realistic ‘jiggling’ of body parts (breasts, ass, etc). The material is more elastic which allows the dolls to be more flexible at their joints. Good heat retention. Less expensive. Safe for human contact Less durable than Silicone - more care is required to clean and care for it properly. The medical silicone material or medical-grade TPE dolls do not contain any harmful, toxic, or itchy material or chemicals. The medical Silicone material or TPE sex dolls are sterilized and made with similar components as sex toys. The idea is that the sex doll simulates what it feels like to have actual sex with a real person. It is built to match as closely as possible the real person on which it was modeled, right down to the fact that it is heavy like a person. It is the same height as a petite woman, too. For all intents and purposes, your sex doll is a person who does not talk or move, but it otherwise fully functional.
