Thank you for viewing! This is a simple book cover. It's made from the new Avio (blue) color of the popular Italian leather, MARGOT. I think it's a color close to light blue or turquoise blue among blues. The actual product is slightly darker than the photos. 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 enjoy the aging process. ・Product Size (outer dimensions): 29.9cm x 16.2cm The inner height is 154mm. It supports tall paperback sizes (height 152mm) from major publishers. Also, it's 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 41 ・Weight 61g The fifth photo shows a Kodansha Bunko book with 380 pages, and the sixth photo shows a Bunshun Bunko book with 580 pages inside. ※ As a reference, I've uploaded a comparison photo of the aging process of a blue paperback cover in the last photo. I apologize that there isn't one for Avio 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.
