CISTA , which uses tanned leather and canvas, is a product that is difficult to care for at home. (Dark Navy uses tanned cowhide leather.)

In addition, Nume leather is vulnerable to moisture such as rain, so if you are worried about it, we recommend using a waterproof spray before you start using the bag.

[About waterproof spray]

For leather products, use fluorine-based materials that are breathable and waterproof without damaging the texture of the leather .

*Fluorine-based waterproof spray can be used on both leather and canvas.

The water-repellent effect of fluorine-based waterproof sprays does not last very long, so if you want to keep your bag clean for a long time, we recommend using a waterproof spray regularly.

Be sure to use the waterproof spray outdoors in a well-ventilated area, wear a mask to protect your mouth, and be careful not to inhale it.

    [How to use waterproof spray]
  1. Remove dust and dirt from the bag with a soft, clean cloth or brush before applying waterproof spray.
  2. Outdoors in a well-ventilated area, keep a distance of about 30 cm from the main body of the bag and spray evenly over the entire bag.
    To avoid spraying the brass fittings as much as possible, protect the fittings with paper or the like before spraying.
    The amount of waterproof spray applied should be enough to lightly dampen the surface of the bag.
  3. Let it dry in the shade for 30 minutes.
    Always dry in the shade, as drying in direct sunlight can leave spray marks.
    Immediately after spraying, the leather part will change color as if it were wet, but it will return to its original state when it dries, so please do not rush and dry it thoroughly.
  4. After the surface is dry, gently wipe it with a soft, clean cloth.
    An old T-shirt or similar can be used, but be sure to use a clean, soft cloth.

If you put a drop or two of water on something that has been coated with a waterproof spray, you can see that the water is repelled like this.

As time passes while it is wet, it will gradually soak into the leather, so please wipe it off with a dry cloth quickly. After about 5 minutes, it will be completely dry.

On the other hand, if the waterproof spray is not applied, it will soak into the leather as soon as you put water on it.

Five minutes after wiping off the water droplets, it has become a faint ring stain like this.

About aging of Nume leather

Tanned leather is vegetable tanned leather.

Since the surface is not treated, you can feel the original smell and feel of the natural material "leather", and you can enjoy the change over time. Before use, it is a natural beige with a slight pink tint, but the color will darken as you use it. In addition, when exposed to sunlight, it becomes glossy, and the oil from your hands absorbs it, turning it into a beautiful amber color.

When I compared the parts that were stored in a sunny room for about a month, there was this much change in color.

In addition, the more you use Nume leather, the less oil it contains and the more it dries out. Regular moisturizing with leather cream will keep the leather in good condition. Please enjoy the feeling that grows as you use it.
