Thank you for viewing! This is a simple book cover. It's made from BROWN Italian leather, MARGOT. MARGOT is a European cowhide leather tanned with vegetable tannins and has a scratch finish. As you use it, the leather will develop a patina, becoming shinier and the color will deepen over time. We hope you enjoy the aging process. ・Product Size (outer dimensions): 29.8cm x 16.3cm The inner height is 154mm. It fits most major publishers' tall paperback sizes (152mm high). It's also designed to be folded 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 171 ・Weight 63g The fifth photo shows a Kodansha Bunko with 380 pages, and the sixth photo shows a Bunshun Bunko with 580 pages inside. ※The last photo shows a comparison photo after aging with a blue paperback cover for reference. We apologize that we don't have a BROWN one that has aged yet. Due to the genuine leather and handmade nature, there may be slight wrinkles or scratches. We hope you enjoy them as unique characteristics. Please check the photos and understand before purchasing. Shipping will be via Yu-Packet Post Mini, folded. We apologize, but please refrain from comments requesting price negotiations. Color: Brown Pattern/Design: Solid Material: Genuine Leather Type: Book Cover
