Definition: For modern dolls, a ball-jointed doll is a doll generally made in Japan or South Korea (although also made in the United States and China) that features ball joints. Ball joints are joints using a round ball-like mechanism that allows the dolls a full range of movement. The first dolls considered ball-jointed dolls were very realistic with an anime look and feel, although today there are also child dolls and other styles of dolls that are considered ball-jointed dolls. The vast majority of ball-jointed dolls are made of resin, although some are made in vinyl. Nearly all are highly customizable by their owners (eyes, limbs, wigs and more can be customized; in fact many might argue that a doll that is not easily and highly customizable is not a ball-jointed doll).
In antique doll usage, ball joints are a common method of jointing composition bodies; uses little wood "balls" at joints for movement.
