?What’s Blind Box? “BLIND BOX” is a type of sealed packaging that keeps what’s inside a mystery until you open it. Some are rarer to find, which we call “SECRET” figures. For example, if you order a “Set of 12 Boxes”, you will receive a set of 12 figures in 12 different designs. Note: If there is a “secret” figure in the set you received, one basic figure will be randomly replaced.
