In the mainland of China, the most common name is real sex doll, which may be called solid sex dolls because these artificial lifelike sex dolls are all solid. In addition to the name of the realistic real doll, the names of sex dolls, adult sex dolls, silicone love doll, and simulation dolls are often used. Silicone dolls are also commonly used names, which is because early artificial lover dolls were made of silicone, so the simulation of dolls is equivalent to silicone sex dolls. Today, TPE (thermoplastic elastomer) has become a common raw material for doll making on the market, but there are still many consumers who cannot distinguish between TPE and silicone. So many consumers have bought TPE full size sex doll, but he thought what he bought was the so-called silicone real life sex dolls.
