These are goods from BTS' "PERMISSION TO DANCE ON STAGE" concert. I purchased them from the official online store! The back side has individual messages. This is a set of all 7 cards. I opened them once to check the contents. After that, they have been unused and stored in a dark place. To prevent any trouble, returns and exchanges are not accepted. *Please purchase only if you understand that these are stored by a private individual. Thank you for reading this far!
