This is a postcard set featuring original drawings from "Demon Slayer: Kimetsu no Yaiba - Mugen Train Arc" (Episode 2 & Episode 6). There are two sets, totaling 10 cards. I opened them once to check the contents, but immediately put them back in a new OPP bag. They have been stored in a dark place, so I don't think there are any major issues, but there may be some initial scratches that are only visible when held up to the light. Also, as these are paper products that have been handled by a person, please refrain from purchasing if you are looking for items in perfect, like-new condition, or if you are sensitive to the condition. They will be shipped together in a waterproof OPP bag and reinforced with thick cardboard on both sides via Mercari delivery service. Thank you very much. ufotable Cafe
