Hand-stitched genuine leather notebook cover for Traveler's Notebook Passport Size. It can hold a total of 3 notebooks: one in each of the left and right pockets, and one in the center elastic band. If you use connecting elastics, you can store two notebooks in the center, so I think you can store up to 4 notebooks in total. It comes with a pen holder with adjustable thickness. In the photo, a uni-ball one P is inserted. I think it can be used for pens up to about 15mm in thickness. The outer leather is Bulgaro cognac from Italian leather, and the lining is black nubuck leather. Black Vinymo thread was used, and the edges were polished with Tokonole. The center elastic band is dark brown, resulting in a calm design. *Also listed on other sites.

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 that I recommend when creating elegant and tasteful works. In terms of physical properties, it is vegetable-tanned, dye-finished, and made using the vacchetta method, so the leather is well-oiled. It will change to a deep color the more you use it, and it will develop a natural luster, allowing you to enjoy the aging process. In addition, the back is processed and the leather is pressed, further tightening 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 keep this in mind as a reference. Color-fixing treatment is not applied to prioritize the original texture of the leather, so there is a possibility of discoloration, fading, color transfer, and oil transfer. Please understand this beforehand.
