What exactly is a delf doll (ball-jointed doll) ?
Real BJDs (ball jointed dolls) are generally resin dolls made in Asia. The name is from the fact that the body parts are all separate pieces – the lower arm is separate from the upper arm, the hand is separate from the lower arm etc. These pieces meet in ball and socket joints that are only held together by the elastic stringing of the doll. Sometimes the lower piece will have a built in ball end and the upper piece has a scooped in “socket” shape to match the ball. Sometimes the balls are separate and the body sections all end in sockets. There are some vinyl true BJDs made in the US (like Goodreau American BJD) but in general these are not accepted on the largest US BJD board, Den of Angels due to their American look and proportions. Real resin BJDs come in 4 basic sizes – tinies (everything under 35cm or so), MSD or mini or 1/4 size (40cm-46cm), SD or 1/3 size (56-64cm) and a less common larger size around 70cm. The minimum prices run for about $90 for the cheapest tiny, Under $200
