Thank you for viewing. This is a handmade item. It fits a paperback book (15.2 x 10.6 cm). A simple book cover made from indigo blue cowhide (leather with a natural wrinkle texture and a slight firmness) finished with navy stitching. Because it's genuine leather, it will develop a nice texture the more you use it. Size: Approximately 16.4 x 24.5 cm (photographed with a 15.2 x 10.6 cm paperback book) * Regarding the leather used in production: We select leather in good condition that allows you to enjoy the texture of the leather. However, natural leather may have original scratches, blemishes, 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 less slippery, so it may require a little technique. However, the leather will soften with use, making it easier to set the book. * Regarding custom orders: We do not keep leather in stock and find it difficult to obtain the leather you may want, so we do not accept custom orders. The leather purchased for production is almost entirely used up, so the book covers we sell are unique, one-of-a-kind items. * Regarding bookmarks: Bookmarks (eyelet hardware, leather string, round leather) can be attached. The fee is 100 yen. We have several colors of eyelet hardware, leather string, and round leather available for you to choose from. Please inquire if you would like one. * We do not offer discounts on single handmade items. For those who purchase two or more items together, we will offer a small discount. 100 yen off for two items, 200 yen off for three items, 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
