more in information here, I'm a doll collector and own some of them just be careful of customs, they can be grabbed in japan just get a good yahoo japan auction website (like SMJ) from there, look for cutomized figures and such dolls.
mind you its not cheap this is not a 150-200 hobby. in yahoo japan so mostly in bidding format, just won a good modeled custom kirino figure cost for 57k, though my dollfie dream is much worse than that.
need more help drop me a pm.
