Thank you for viewing. I purchased this book at a bookstore this month and have read it once. Since it has been read once, there is some wear and tear. It's difficult to see in the photos, but there are crayon marks from a child. Please check photos 8 and 9. Please purchase with the understanding of the above-mentioned stains. "Golden Ratio's Edge" Natsuko Ishida Price: 473 yen (tax included) Please refrain from purchasing if you are looking for a product in new condition or if you are concerned about minor details, as this item has been handled by another person.
