"Daijirin" Sanseido Editorial Department / Akira Matsumura Thank you for viewing. I purchased this in June 2024 for my middle school son, but he hardly used it, so I am selling it. There is a crease at the bottom of the cover case band. (Please check the 10th photo) The serial code is unused. Overall, it is in a clean condition with little use, but please consider this item if you understand that it is a used item.
