Thank you for viewing! This is a simple book cover. It's made from Nero (black) 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): 29.9cm x 16.2cm The inner height is 154mm. It fits most major publishers' tall paperback sizes (152mm high). It's also a fold-over style to accommodate the thickness of the book. MARGOT is 1.4mm thick, but it's soft and has a calm, moist feel, so we hope you enjoy the texture. ・Thickness of MARGOT used 1.4mm ・Thread Vinymo MBT #5 Color number: Black ・Weight 66g The fifth photo shows a Kodansha Bunko with 380 pages, and the sixth photo shows a Bunshun Bunko with 580 pages inside. ※For reference, the last photo shows a comparison photo after aging with a blue paperback cover. We apologize that we don't have a Nero aging example yet. 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.
