【New Year's Sale】 If you purchase with other books, we may be able to offer a discount on shipping costs, so please feel free to inquire. Oshiri Tantei (Butt Detective) series. I also have other single books and picture books for sale. The inside is relatively clean, but there may be some tears or scratches on the outer cover. Also, since these are books that children have read, there may be some unconfirmed stains or folded corners. I also have paperbacks and picture books for sale. If you wish to purchase multiple items, I can offer a discount, so please comment. Please understand that these are books that children have read and have been stored at home by a non-professional. During comments, please refrain from purchasing. Please note that while negotiations are ongoing in the comments, I may temporarily pause the listing, but if someone else purchases before that, I apologize, but I will prioritize the person who made the purchase. Thank you for looking.
