Handmade book cover, for a shinsyo (pocket-sized) book. The height is about 17.5cm, a typical size. The width can accommodate books up to 25cm in total for the front cover, thickness, and back cover, making it suitable for thicker books. It should also fit children's literature series like Iwanami Shonen Bunko. The leather uses cowhide that has been sanded on the surface. It has a matte texture and a gentle touch, creating a soothing leather feel. You can also enjoy the aging process. I purchased this on a handmade website, but I haven't had a chance to use it, so I'm putting it up for sale. No price reduction. No pets, no smokers.
