All dolls must be made of resin. This means they must be cast in a liquid two-part system using a mold (usually silicone). All dolls made of injection-molded plastic or vinyl\* cannot be included in this database. ​Resin 3D printed dolls are okay, as long as they are strung, jointed, and do not have rooted hair.

All does must be held together by elastic cord or string. Dolls that have an internal posable structure are not allowed. Dolls that have a "hinge" joint are not allowed.

Rooted hair means the doll's hair is pushed through a series of holes in the head. Examples of dolls with rooted hair are Barbie and Monster High.

Molded hair is okay. Molded hair is defined as removable or permanent resin hair.

Dolls that are massed produced are usually done so using plastic and injection molding machines in an automated factory.

Basically, if you can go pick up a doll in a supermarket or similar store, the doll is not allowed.

As long as the doll fits into all the above criteria, the doll is allowed. The doll has to be jointed in some way. Solid resin objects with no jointing are not allowed.
