What is blind box stationery?

Blind box stationery means that the outer packaging of blind boxes is "blind" and there are so many surprises. There is no note on the box. You can't know what's inside until you unpack it. The words printed on the outer packaging of the box are also very attractive: the chances of winning the prize are beyond your imagination, and you can earn it if you buy it. With luck, five dollars can buy valuable stationery. If you are unlucky, you may only have an eraser or a one-dollar pen. Its model is similar to the previous crisp card and it is sold in Japan.

The blind box originated in Japan, and its logic is similar to the crisp-faced card game more than ten years ago. Nowadays, most blind boxes are fashions derived from various anime characters. Blind boxes in the same series have fixed models and hidden models respectively, and the probability of hidden models is extremely low because of different proportions.
