The card game "Show Me Your XX," a unique creation from the Treasure Museum. It can also be used as a deck of playing cards. This is a card game based on a manga by Nonki Miyasu, which I found while cleaning. It has been stored for a long time. The instruction manual has some discoloration, but the cards appear to be in good condition without any folds or noticeable stains. (Please note that this is a visual inspection, so there may be some oversights) All the cards are present. There are lines written on the box with a pen. Please check the photos. Thank you for looking.
