Dear BlueMoon, Thank you for your review and consideration. Although the bookmark you requested is not in the photos, I will enclose it. Thank you for looking. I have made these items using the popular Italian leather MARGOT (Margot) in Alloro (green) & Lilla (pink). MARGOT is leather made from European cowhide tanned with vegetable tannins and has a scratch finish. The color will deepen and develop a luster over time with use. We hope you enjoy the aging process. ◎ Paperback book cover Alloro (green) ・Product Size (outer dimensions): 30.0cm x 16.2cm The inner height is 154mm. It supports tall paperback sizes (height 152mm) from major publishers. Also, it is a folding type to accommodate the thickness of the book. MARGOT is 1.3mm thick and has a slightly firm but soft and calm feel, so we hope you enjoy the texture. ・Thickness of MARGOT used 1. 3mm ・Thread Binimo MBT #5 Color number 136 ・Weight 67g The 6th photo shows the cover with a Kodansha Bunko paperback of 380 pages, and the 7th photo shows the cover with a Bunshun Bunko paperback of 580 pages. ◎ A5 size notebook cover Lilla (pink) ・Product Size (outer dimensions): 39.2cm x 22.0cm The inner height is 213mm. It supports A5 size notebooks (210mm). MARGOT is 1.4mm thick and still feels a little firm, but it is soft and supple, so we hope you enjoy the texture. ・Thickness of MARGOT used 1. 4mm ・Thread Binimo MBT #5 Color number 16 ・Weight 120g The 13th photo shows the cover with a Midori A5 size MD notebook of 11mm thickness. The 14th photo shows the cover with two MD notebooks of 11mm thickness each (22mm) stacked inside. ※The last photo is a comparison photo after aging for about six months with Cobalt. Due to the use of genuine leather and handmade construction, there may be some wrinkles and scratches. We hope you enjoy them as unique characteristics. We ask for your confirmation and understanding with the photos.
