This is a mascot keychain from the Ojarumaru gachapon! There is a white, dust-like substance on the back of Ojarumaru's hair, but it was there from the beginning as it is unopened. Please understand. How about it? We do not accept returns after purchase, so please be sure to check the photos before buying. We do not accept purchases from those who are sensitive about home storage. If there are any parts you would like to see up close or have any questions, please feel free to comment anytime!
