Supia Doll (sometimes styled as Supiadollz) is a South Korean-based maker of ball-joined dolls. Supia is an alias of Yujin, the artist who designs the company's dolls.
Yujin created her first doll in 2004.
The first doll offered for sale by Supia was the Supia60, in a limited run of 20 dolls.
Originally, Yujin used French resin for most of her dolls. This was gradually replaced with a preference for polyurethane resin, and beginning in 2009, the company only offers dolls in polyurethane resin. As of 2010, Supia posted notice that it would no longer carry white skin as a resin colour for its polyurethane dolls. The plan was for the skin tone to be reworked, but as of July (2011) there is no solid commitment for re-release of even a reworked white skin. The tone has been changed twice in the past.
