This is a Demon Slayer clear file, a collaboration with Waseda Academy. My child brought it home in their bag. The one with the "Difficult Problem" text was brought home with materials inside. It hasn't been used since. It wasn't individually packaged, so there may be minor scratches. Please understand. A clear file featuring Demon Slayer characters depicted in the snow. - Characters: Demon Slayer - Design: Characters in the snow - Text: "I don't want to lose. I have friends who make me feel that way." - Collaboration: Waseda Academy x Demon Slayer Thank you for looking.
