A ball-jointed doll (BJD) is a type of doll characterized by its construction. The doll’s limbs are articulated with ball and socket joints, allowing for a wide range of poses. These dolls are typically made from resin, though other materials like porcelain or vinyl can be used. An example includes a doll with individually strung limbs connected to the torso with ball joints, allowing for realistic and customizable positioning.
The articulated nature of these dolls permits a high degree of customization, contributing to their appeal among collectors and hobbyists. This customizability extends to aspects such as wig, eye, and clothing changes, as well as more advanced modifications like face-ups (repainting the doll’s face). Historically, similar jointing mechanisms can be traced back to antique dolls, but the modern iteration, with its focus on resin and extensive customization, emerged in the late 20th century.
