Thank you for viewing. This is a simple book cover. It is made from Alloro (green) of the popular Italian leather, MARGOT. MARGOT is leather made from European cowhide tanned with vegetable tannins and has a scratch finish. As you use it, the color will deepen and develop a luster over time. We hope you will enjoy the aging process. ・Product Size (outer dimensions): 29.9cm x 16.2cm The inner height is 154mm. It supports the height of the bunko book size (height 152mm) from major publishers. Also, it is a folding type to accommodate the thickness of the book. MARGOT is 1.3mm thick and has a slightly firm but calm feel, so we hope you will enjoy the texture. ・Thickness of MARGOT used 1. 3mm ・Thread Binimo MBT #5 Color number 136 ・Weight 63g The fifth photo shows a Kodansha Bunko book with 380 pages, and the sixth photo shows a Bunshun Bunko book with 580 pages. *The eighth photo is a comparison photo after aging for about six months with Cobalt. I'm sorry, but there is no aging photo with Alloro yet. Also, the color of Alloro is not expressed well, and I think it is a color that is a little closer to grass green. Due to the genuine leather and handmade nature, there may be some wrinkles and scratches. We hope you will enjoy them as individual characteristics. Please check the photos and understand. Shipping will be folded and sent via Yu-packet Post Mini. We are sorry, but please refrain from comments asking for price negotiations.
