#Genuine Leather #Handmade Made with deep dark brown leather. It has a fine grain on the surface and a slight sheen, giving it a luxurious feel, and the flesh side is also beautiful. The firmness is medium, and it's a sturdy leather with a slight squeak. The sewing thread is linen thread, and everything is hand-sewn, so it's durable. The size when open is 315mm wide and 213mm long. A Kodansha paperback book with 500 pages was used for the photos. The book itself measures 195mm in length, 140mm in depth, and 34mm in thickness. Since it is natural leather, there may be scratches, wrinkles, and color unevenness, but please take a good look at the photos before purchasing.
