This is an acrylic keychain of Ba-u from Knight A - Knight A - (currently Knight X). I purchased it from the official store several years ago and have kept it in a dark place without opening it. I do not have any pets, and I do not smoke. Please refrain from purchasing if you are sensitive to the condition of the item, as it has been stored by a private individual. It will be shipped via Yu-Packet Post, so it is an anonymous delivery. Instant purchase is OK. Please feel free to comment if you have any questions. ↓↓↓Search terms↓↓↓ Knight A, Knight X, Ba-u, STPR, acrylic key chain
