"Chart-Shiki Basic Mathematics 3" Chart Research Institute Price: ¥1960 The outer cover has some damage such as scratches and wrinkles, but the inside has no damage such as writing, stains, or folds, and is a nearly unused, excellent condition item. I think you can still use it comfortably. Thank you for your consideration, understanding the above. #ChartResearchInstitute #Book #Other/Other
