For girls in idolize, especially fans who like to collect small cards, a small card is printed with beautiful photos of their love beans, so small cards are valuable in their eyes. The number of small cards in different groups is different, depending on the official configuration. There may be many kinds of cards, such as signature cards, laser border cards, triangle cards, etc., and some albums are just one.

Printing celebrity cards, making data lists and spending money to buy celebrities are all daily activities of idolized people.
