This is a set of 6 Agatsuma Zenitsu merchandise items from Demon Slayer. Although unused, these items have been handled by someone else, so please refrain from purchasing if you are sensitive to this. The square keychain on the front has a mirror on the back. The items in the bags have never been opened since I received them. The rubber strap does not have a ball chain. The small can badge has a cover, but the safety pin on the back has some rust because it's 4 years old. Please be aware of this. Instant purchase is available.
