This is an outlet item due to a slight difference in the width of the rubber bands at the top and bottom. The width is 9mm x 2, but one side is 14mm. Since the notebook is held in place by the rubber bands on the outside, there is no problem with use. If you don't mind, please consider it. It's also easy to distinguish the top and bottom. The top image is a representative image. The item for sale is the one wrapped in bubble wrap in the third image. Brown rubber bands are used. ----------------------------------- This is a passport-sized notebook cover made of genuine leather (vegetable-tanned leather). It can also be used as a cover for Traveler's Notebooks and Muji passport-sized notebooks. Vegetable-tanned, natural-colored leather, no surface treatment. This type of leather ages rapidly and turns amber. I try not to touch it as much as possible during production and store it in a dark place. 【Reason for rapid aging】 Because it is uncolored and unprocessed, it reacts directly to light, hand oils, and moisture in the air. Within a few days to weeks of use, it will turn a light amber color. Within a few months, it will develop a clear luster and a deep color. The charm is that the user's habits and time are engraved on the leather's appearance. For the first few days, you can put it in direct sunlight for about 15 minutes to "bake" it (this can reduce color unevenness). Protecting it with oil or mink oil before you start using it will also prevent water stains. This leather is worth nurturing, so please enjoy the changes and use it well. The leather is about 2mm thick, and because it uses natural leather, there may be wrinkles, scratches, and color unevenness that the leather originally has. You can enjoy the aging process. You can hold one notebook with the built-in rubber band. You can hold +1 to 2 notebooks with the external rubber band. I will send it to you with three notebooks inserted, so you can use it immediately. (One external rubber band and three plain notebooks are included) Cover size Width: Approximately 21 cm (when opened) Height: Approximately 13.5 cm This is a handmade item by an amateur. Please forgive any slight errors. If there is no significant difference in the images, I reuse them. → The top image is a representative image.
