[Product Description] ・This is a simple, handmade book cover made from a single piece of leather. ・The folded-over part, which is touched most often, is designed for a smooth feel compared to covers sewn from two pieces. ・Insert the book's cover into the folded-over part. ・Compatible with paperback books, approximately 15cm tall, 10.5cm wide, and 3-3.5cm thick. ・Since paperback book covers are generally thin, the cover is made a little loose for easy insertion. You can insert the cover along with the book's cover. ・The cover has a large gusset, so it can be used with thick books (up to about 3-3.5cm thick). (Conversely, it is not recommended for books with a thickness of about 1.5-2cm, as the cover will be too loose) ・Photos (1-4) show the cover with a book that is 15cm tall, 11cm wide, and 3cm thick. Photos (5-6) show the cover with a book that is 15cm tall, 11cm wide, and 2.5cm thick. ・Made of soft sheepskin, it is very light, and the surface has a fine wrinkle pattern.
