Thank you for viewing. This is a handmade item. It fits paperback books (15.2 x 10.6 cm). Made with black embossed cowhide (Thin, matte, and slightly firm leather) This is a simple book cover finished with black stitching. Special type: Can be used for paperback books up to 3 cm thick. Since it's genuine leather, it will develop a nice texture the more you use it. Size: Approximately 16.2 x 25.4 cm (for paperback books 15 x 10 x 1.6 cm thick) * Regarding the leather used for production: We select leather in good condition and that allows you to enjoy the texture of the leather. However, natural leather may have original scratches, scuffs, variations in color, and unevenness on the back. We hope you will enjoy these as natural characteristics. Please be sure to check the images and understand the characteristics of the leather before purchasing. * Regarding use: When setting the book, the leather may be slippery, so it may require a little technique. However, the leather will soften with use, making it easier to set. * Regarding custom orders: We do not keep leather in stock and it is difficult to obtain the leather you desire, so we do not accept custom orders. The leather purchased for production is almost completely used up, so the book covers we sell are unique items that we hope you will enjoy. * Regarding bookmarks: Bookmarks (eyelet hardware, leather cord, round leather) can be attached. The fee is 100 yen. We have several colors of eyelet hardware, leather cord, and round leather available, so you can choose. Please inquire if you wish. * We do not offer discounts on single handmade items. For those who purchase two or more items together, we will offer a small discount. You will receive a 100 yen discount for purchasing two items together, and a 200 yen discount for purchasing three items together, so please be sure to inquire before purchasing. * If you have any questions or requests, please feel free to contact us. Thank you. #leather #bookcover #cowhide #paperback
