Unique and strange world of "rounded corner cards"

Not just for collection, "rounded corner cards" have also become a means of communication and a part of fandom culture.

Fans often trade and transfer to collect the cards they want to own.

"Corner cards" are small-sized photos printed with idols, randomly placed in albums. Fans continuously buy albums to have their favorite "corner cards". It would be a pity if the precious "corner cards" were crumpled or torn. Fans have invested in additional top loaders (transparent plastic cards) to protect the cards when carrying them with them. The world of "corner cards" has become richer and more interesting thanks to the top loader decoration trend. With just stickers, self-drying clay, glue, charms (decorative beads with cute, funny shapes), fans can freely create, turning top loaders into extremely eye-catching virtual accessories. "Poka ritual" is also gradually becoming popular in young people's lives. This is the moment when fans take out their favorite "corner cards" and take photos while eating delicious food or traveling, to preserve the joy with people who share the same interests.
