✴️ This product is a set of 5 books. Due to shipping costs, we do not sell them individually. Thank you for your understanding. ✴️ Only the text in the second photo has a brown stain on the front cover. The other 4 books do not have any noticeable stains, but they are used items, so please purchase only if you understand this. We do not accept returns, exchanges, or complaints. ✴️ All 5 books have no writing in the pages with pens or other writing instruments. There is no water damage or stains. ✴️ Because of the thickness, we will ship them in a cardboard box via Yu-Pack for your peace of mind! ✴️ Price reduced from 7777 yen!!
