Originally made in Japan, Korea, and China of high-quality resin, these dolls have multiple joints. Modern doll artists in the United States and other countries are now producing ball joint dolls in resin and vinyl.
These dolls are meant for adults, not children. They are made to be modified, and their owners can paint the faces (called "face up") and change the wigs, eyes, and even body parts, making the dolls their own unique creations. Some dolls come with interchangable faces.
Nancy shared dolls from her own extensive collection, and many members brought their own ball joint dolls.
