I don't know about the new BFC ink (the ones with jointed arms/wrists) but the old ones are strung and it's a pain in the butt to get out all the elastic. Each one of the pieces are attached to these little plastic washer things. bah It's not worth the trouble.
There is also Little Miss Matched dolls, I don't think they have jointed wrists or ankles but they are on the slim side and about the size of a msd. The only place I think you can get them at is TRU and they are in the same isle with the other Little Miss Matched stuff.
