Dear Makura, Thank you for waiting. Please take a look and consider. Thank you for viewing. This is a simple book cover. It was made with the new colors Avio (blue) & Rosa (pink) of the popular Italian leather MARGOT. Avio is a color close to asagi-iro (pale blue) or turquoise blue among blues. I think the actual product is slightly darker than the photos. Rosa is a color close to rose pink, coral pink, or pale red among pinks. 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. ◎Avio ・Product Size (outer dimensions): 29.9cm x 16.2cm The inner height is 154mm. It supports the tall paperback size (height 152mm) of major publishers. Also, it is a fold-over type to accommodate the thickness of the book. MARGOT is 1.3mm thick and has a soft, calm feel, so we hope you will 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. ◎Rosa MARGOT is 1.4mm thick, but it is soft and has a calm feel, so we hope you will enjoy the texture. ・Thickness of MARGOT used 1. 4mm ・Thread Vinymo MBT #5 Color number 140 ・Weight 64g ※For reference, the last photo shows a comparison photo after aging with a blue paperback cover. I apologize that there are no aging photos for Avio & Rosa yet. 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 via Yu-Packet Post Mini, folded. We are sorry, but please refrain from comments requesting price negotiations.
