Thank you for viewing. This is a set of 4 bonus cards from AKB48 Shinobu Mogi's graduation photobook. They are postcard-sized, but the back is blank, so they cannot be used as postcards. All 4 cards will be shipped in sleeves. They have never been taken out of the sleeves, so they are treated as new and unused. Immediate purchase is OK. Thank you very much!
