※ This is a used paperback book. I have nearly 2,000 books for sale, so please search for your desired book using "[Discount for multiple purchases] 〇〇〇" or ask in the comments section. If you purchase multiple paperbacks I have listed at the same time, the prices are as follows (when they can be shipped together): 2 books: 760 yen 3 books: 1,050 yen 4 books: 1,320 yen For 5 or more books, it's an additional 280 yen per book. Please note that the maximum number of books that can be shipped together is about 8, depending on the thickness. If you wish to purchase multiple books, please let me know in one of the following ways: ● Submit a combined purchase request.
