I received these paper, build-it-yourself masu (square wooden cups) as part of a collaboration between Demon Slayer (Kimetsu no Yaiba) and Komeda Coffee. I received three, assembled one for use, and have kept these two remaining ones unassembled. How about assembling them with your children for Setsubun (bean-throwing festival) or other occasions! The masu can also be used as small item containers. I will package and ship them via anonymous delivery. Thank you for looking. - Design: Masu with character illustrations - Material: Paper
