Dear MT, Thank you for waiting. Please review and consider. I have also enclosed the bookmark you requested. Thank you for viewing. This is a simple, custom-made notebook cover. It is made from popular Italian leather, MARGOT (Margot), in Castagna (dark brown). MARGOT is leather made from European cowhide tanned with vegetable tannins and has a scratch finish. As you use it, it will develop a patina and the color will deepen over time. We hope you will enjoy the aging process. ・Product Size (outer dimensions): 31.5cm x 21.5cm The inner height is 207mm. The inner pocket is 50mm wide. MARGOT is 1.4mm thick and has a slight firmness, but it is a soft and calm leather, so we hope you will enjoy the texture. ・Thickness of MARGOT used 1.4mm ・Thread Vinymo MBT #5 Color number 125 ・Weight 102g The color in the 6th photo was not well represented, so I took a picture with white paper as a background. I think this is the closest color. *I have uploaded a comparison photo after aging with a blue paperback cover in the last photo for reference. I apologize that there is no aging example for Castagna (dark brown) yet. Due to the genuine leather and handmade nature, there may be slight wrinkles and scratches. Please check the photos and understand. Color: Dark brown Pattern/Design: Solid Material: Genuine leather Type: Notebook cover
