Until 2009, Supia dolls were offered for sale in the United States through Dollfair International, but now Supia sells directly to customers.
Originally, Yujin used French resin for most of her dolls. This was gradually replaced with a preference for polyurethane resin in 2009. Their current production consists of male and female dolls in 1/3, 1/4 and tiny sizes.
From April 5, 2021, Supia offered new colours of resins: White, Cream White, Light Rose White, Rose Pink, Peach, Real, and Milk Brown. Previous resin colours have been discontinued.
