The competition between torso sex dolls and granny sex dolls for global market share is deeply rooted in the complex global supply chain competition and the art of cost control. With its mature manufacturing ecology, complete chemical material supply system and relatively low labor costs, China has become the absolute main force in the global production of the torso sex doll, dominating the mid-range and lower markets. Japan, Europe and the United States maintain technical or brand premium advantages in the fields of high-end silicone dolls, precision mold manufacturing and special designs (especially some highly artistic or realistic granny sex dolls).

When the idol industry advocates plump curves, the flat chested sex doll unexpectedly becomes popular. User data from the Hongdae store in Seoul shows that 70% of buyers choose the life size sex doll with a bust of less than 70cm. Psychologists point out that this is a rebellion against appearance anxiety - consumers fight against the aesthetic hegemony in reality by controlling the silicone body.
