Thank you for viewing! This is a simple book cover. It's made from Alloro (green) of the popular Italian leather, MARGOT. MARGOT is leather tanned with vegetable tannins from European cowhide and has a scratch finish. As you use it, the color will deepen and develop a luster over time. We hope you enjoy the aging process. ・Product Size (outer dimensions): 30.1cm x 16.3cm The inner height is 154mm. It fits most major publishers' tall paperback sizes (height 152mm). It is also a fold-over style to accommodate the thickness of the book. MARGOT is 1.3mm thick and has a soft, calm feel, so we hope you enjoy the texture. ・Thickness of MARGOT used 1.3mm ・Thread Vinymo MBT #5 Color number 136 ・Weight 65g The fifth photo shows a Kodansha Bunko with 380 pages, and the sixth photo shows a Bunshun Bunko with 580 pages inside. *The eighth photo is a comparison photo after about six months of aging with Cobalt. I apologize that there is no aging photo for Alloro yet. Alloro's color is difficult to capture well, but I think the last photo is the closest color. Due to the genuine leather and handmade nature, there may be slight wrinkles or scratches. Please check the photos and understand before purchasing. We apologize, but please refrain from comments requesting price negotiations. Type...Book cover Pattern/Design...Solid Material...Genuine leather
