Animation co-branding, scratch-off surprises, social currency... many primary school students went to stationery stores as soon as school was over.

One child spent 3,500 yuan on blind box pens and blind box erasers. Parents worry: excessive consumption is detrimental to the healthy growth of children. For children, buying a blind box pen is actually buying animation peripheral products. Among them, the more common animation IPs include Ultraman, Eggman Party, My Little Pony and SpongeBob SquarePants.
