Thank you for viewing! This is a non-sale, purchase bonus playing card set for the Game Boy Advance game "Power Pro Kun Pocket 7," released in 2004. It is unopened. 6cm x 9cm It was found during a home clean-up. It has been stored in a dark place, so there is no sun damage and it is in good condition, but it is a long-term home storage item. I would like to sell it to someone who understands this. Thank you very much!
