Pullips and Junk 
I have just discovered these dolls and am interested in finding more. Where can I find more at reasonable prices? My hope is they will make more! I will not be reselling them to make money. I just love them!
Check out amazon for some reasonably priced J-dolls. Unfortunately J-doll is done, the last one announced was canceled and that was over a year ago. They are now selling for far below the wholesale price so Groove ended up losing a fair bit of money on them so I honestly don’t see them making more of a product just to lose money on it ^^;
