Kadokawa Manga Study Series: History of Japan, Complete 16-Volume Set + 5 Supplementary Volumes (with bonus items) *Bonus items are unused (only opened for inspection during this packaging) Please check the photos for the contents and condition. Purchased in December 2024 for my child's junior high school entrance exams. Only read a few volumes once or twice. Basically in near-new condition, but as this is a used item, please refrain from purchasing if you are sensitive to imperfections. *However, there are folds on the top of the covers of volumes 1 and 4 (please see the photos). I am not considering lowering the price at this time.
