This is a "TeraKata-kun" card featuring Katakamuna characters printed on terahertz paper. It's a set of 3 cards: Verse 5, Verse 6, and Verse 7. It has been stored new and unused. Katakamuna characters are geometric characters passed down from ancient times. The cards, which combine these characters with terahertz, are used for keeping nearby or carrying around. They are compact and easy to fit in a wallet or planner. They are still in their original packaging. Size: Approximately 91 x 55mm Material: Paper (60kg, 3 types x 2 each) I will sell this to someone who understands that it has been stored at home.
