If the world were different!!! This is an acrylic keychain of Seitaro Nakayama from the 2025 Spring Tour goods. I took it out only once, and after that, I stored it in a dark place. There are no noticeable stains, but please refrain from purchasing if you are sensitive to this, as it is stored by a private individual. Please purchase only if you understand that there is no outer bag. Instant purchase is available.
