There were stains like those in photos 10-12. I would appreciate it if you could confirm them. After purchasing new from an online store, I stored the item with a clear book cover and removed the cover for inspection. The yellowing often appears whiter than it actually is in the photos. Furthermore, initial scratches and scratches from aging are difficult to capture in photos. This is a used item. I would appreciate your understanding if there are yellowing, scratches, or corner folds. For combined purchases, I will offer a price of 899 yen for two books. I would appreciate it if those who understand that this is a personally stored item inspected by an amateur would purchase it.
