This is a hand-stitched genuine leather notebook cover for a Traveler's Notebook Passport size. It can hold three notebooks: one in each of the left and right pockets, and one in the center elastic band. By using connecting elastics, you can store two notebooks in the center, so I think it can hold up to four notebooks in total. It comes with an adjustable pen holder. In the photo, a uni-ball one P is inserted. It should be able to accommodate pens up to about 15mm in thickness. The outer leather is Bulgaro cognac Italian leather, and the interior is Tochigi Leather's natural vegetable-tanned leather. White Vinymo thread was used, and the edges were polished with Tokonole. Brown was used for the center elastic, resulting in a calm design. *This item is also listed on other sites. If it sells quickly on another site, I will cancel the order. Please understand. *The following is quoted from the Kawamura Leather website: About 'BULGARO' Leather This is a standard shoulder leather manufactured by Lo Stivale in the Santa Croce region of Italy, with a smooth surface and fine grain. It's a slightly firm leather, but it has a good amount of oil, so I think you'll get the impression that it has "firmness but is also moderately supple." The grain is fine, and there are natural color variations due to the dye finish, making it a leather I recommend when creating elegant and tasteful works. In terms of physical properties, it is vegetable-tanned and dye-finished, and the leather is well-oiled through the vacchetta method, so it will change to a deep color the more you use it, and you can enjoy the aging process as it develops a natural luster. In addition, the back has been treated and the leather has been pressed, further compacting the fibers, making it very suitable for polishing and finishing the edges. About the Aging of 'BULGARO' It will develop a luster and change to a deeper color the more you use it. The aging process will vary depending on the usage conditions, so please consider this as a reference. Color-fixing treatment has not been applied to prioritize the original texture of the leather, so there is a possibility of discoloration, fading, color transfer, and oil transfer. Please be aware of this.
