I know this doll is very rare, I'm dead serious. It's very very rare. And there are 600+ dolls if I'm not mistaken. So i would probably say, you won't be able obtain another kolya even if you open 600+ sd plus blind box. Well if you are lucky, I guess you will. Maybe it would take a year before you can get another one of this doll.
So i want to ask you, how much is the lowest you can go?
