This is an acrylic keychain of Karin Fujiyoshi from Sakurazaka46, purchased at the "Shin Sekai" event in 2023! The postcard is unopened, and the can badge was only used on the days of the live performances with a cover on it, and otherwise stored away from dust. Although there are no noticeable stains or scratches due to the cover, please understand that this is a personal storage item. Thank you for looking. Instant purchase is OK.
