Demon Slayer: Kimetsu no Yaiba - Mugen Castle Arc - Chapter 1: Akaza's Return This is the second round of bonus items for theatergoers. I opened it to check the design, but then put it back in the original silver bag and stored it in a cool, dark place. Thank you for looking. When shipping, I will reinforce both sides of the clear card in an OPP bag and the silver bag in an OPP bag with cardboard, waterproof them, and then put them in an envelope.
