In the era of personalized consumption, the modular design of the new sex doll has opened up a new path to enhance realism. Users can freely combine the local features of the torso sex doll according to their preferences, and can accurately adjust everything from waist size to skin gloss. The introduction of 3D scanning technology allows real body data to be imported into the manufacturing system, achieving highly customized replication. This "tailor-made" model allows each torso sex doll to have a unique biometric signature, greatly reducing the homogenization problem caused by industrial mass production.
