, often abbreviated SD, is a brand of ball-jointed doll, or BJD, made by the Japanese company Volks. They are made to be easy to customize and are primarily marketed to adult doll collectors and customizers. They are cast in polyurethane resin, a porcelain-like, hard, dense plastic. The most common standard models are about 60 cm, or 24 inches, tall, taller and heavier than most comparable Western dolls. They are designed in a style which is both realistic and influenced by anime, and most models are anatomically correct. The various body parts have ball joints for articulation, and are strung together with a thick elastic cord. The term "dollfie" is a portmanteau formed from the words "doll" and "figure". The original Dollfie dolls are Barbie sized vinyl figures, and the term "Super Dollfie" was introduced to distinguish the larger resin dolls. Super Dollfie, or even just Dollfie, are sometimes erroneously used as a generic terms to refer to BJDs made by other companies. However, both Super Dollfie and Dollfie are registered trademarks and should only be used for Volks products. Overview Super Dollfie dolls are made to be easy to customize. The hair is a wig that can easily be changed. The head can be opened to change the eyes and adjust the stringing. The face paint can be removed and the head repainted. Optional hands and feet are available, and heads and other body parts are removable and interchangeable. The resin parts themselves can be carved or sanded to reshape them. Super Dollfie are not widely distributed, and, with a few exceptions, new dolls are only available directly through Volks own events or stores, either online, or through their brick and mortar stores called Tenshi no Sumika (angel's nest), located throughout Japan, in South Korea and until March 2014 in Los Angeles, California. Super Dollfie are collectible, customizable dolls marketed to adults. They vary in price from about 36 000 yen (about US $400) for the smallest, unassembled standard models, up to about 150 000 yen (about US $2000) for the most exclusive larger limited dolls that come with outfits and accessories. On the secondary market, limited and skillfully customized Super Dollfie often fetch a price far higher than the original. There is a thriving second hand market online, where dolls are bought and sold on auction sites, as well as forums. New models are regularly released at Dolls
