POP MART blind box can open the hidden money in the whole box and ask the basic money to make up for it?

POP MART blind box provides a basic model that can be filled with hidden money. In order to increase the user's buying experience, the official launch of POP MART hides money. If we provide hidden money, what else can we ask for to supplement the basic version, because we have such a rule when buying blind boxes. Hidden money means that when the official release of this series of dolls, users will open it and find the hidden money. This surprise experience can be said to be doubled. When finding a doll that others don't know, that kind of happy experience can't be compared with ordinary blind boxes. At present, POP MART has many series, such as Happy Train, Wedding flower girl, Campus Doll, Wedding Commemorative Edition, Palace Doll, Healing Department, Pucky Bubble Circle, Leopard Pattern of Girl Heart Fans, Panther Myth, Constellation Doll, Dream Elf, Dream Ocean, Zodiac Doll and so on. Among them, Happy Train, Wedding flower girl and Pucky Bubble Circle are the most prominent series.
