Care Instructions: It is difficult to manufacture leather tanned by vegetable tannin, due to the fact that it shows wrinkles and scratch marks easily. However, it is also environment friendly and has an authentic attractiveness where the leather will beautifully change appearance over time. The leather used for the TRAVELER’S notebook is coated in oil, and by doing so it makes the finish soft. The Travelers notebook is meant to evoke a natural feeling, so it is not processed excessively and it is normal for small scratches and wrinkles to appear on the cover when you first receive it. The longer you use it, the more the color deepens. And by this deepening, the scratches will become harder to spot. The color dye of the leather is done naturally, so there is a risk of color transferring to an adjacent object when it becomes wet or comes into rubbing contact. When the leather becomes wet through rain or sweat, the color may transfer to your clothes or bag, so please be aware of this when in use. In case it gets wet, please use a dry and soft cloth to absorb the water soaked inside and dry it in a shade. Please avoid using water, benzene, and thinner for this leather. When preserving it, please be aware of any moisture, dirt, and sweat that is on the leather, and store it in a dry place. Please prevent this from sticking to other leather items and vinyl products. The tightness of the rubber band can be adjusted by changing the position in which the knot is being made. Please adjust to your favorite length.
