About natural leather
Genuine leather may have individual differences due to the material, such as differences in color shading, wrinkles, small scratches, blood lines, and grain.
The appearance of the leather may differ slightly from the published photo, but these are also characteristics unique to natural leather.
Also, the actual color may look different depending on the lighting at the time of shooting and the screen you are using.
About color transfer and care
Genuine leather may transfer color to light-colored clothing due to moisture or friction. Please be especially careful on rainy days or when wearing white or beige clothing.
For daily cleaning, gently wipe away dust from the surface with a soft, dry cloth. If it gets wet, wipe it off immediately and let it dry naturally in a shaded area with good ventilation. Please store away from direct sunlight, high temperature and humidity.

Color transfer on leather products may occur due to the characteristics of the leather and dye, friction, etc. However, with proper measures and care, you can prevent color transfer.

1. Characteristics of color transfer on leather products
Color staining on leather products, despite its beautiful appearance and luxurious feel, can cause unexpected problems for owners. This phenomenon occurs primarily as a result of the natural material properties of the leather, the nature of the dyes used, and physical friction.
Color transfer due to the natural material characteristics of leather
Leather is a natural material and its ability to absorb water and retain dyes contributes to color transfer. Especially in new leather products or products that have been treated with oils or waxes that have not been soaked in sufficiently, the dye can easily dissolve when it comes into contact with liquids such as moisture or sweat, making it easier to transfer the color to other substances.
Color transfer due to dye characteristics
The dyes used in the manufacturing process of leather products are intended to improve their brightness and durability, but some dyes have the tendency to transfer color when they come into contact with other materials. This tendency is especially noticeable when exposed to moisture or direct friction, increasing the risk of color transfer.
Color transfer due to friction
Friction between leather products and other substances that occurs during daily use is one of the main causes of color transfer. In particular, when wet leather products rub against clothing, furniture, etc., pigments tend to transfer. Light-colored leather products and products with soft leather textures tend to be more susceptible to this phenomenon.
Understanding these characteristics is essential to minimizing the risk of color transfer when choosing leather products and in everyday use. With proper precautions and care, you can preserve the beauty and functionality of your leather products over the long term.
2. Measures against color transfer on leather products
Color staining on leather products may seem like an unavoidable problem, but you can greatly reduce the risk by taking preventive measures. Below are some effective measures to prevent color transfer.
Precautions when handling new leather products
New leather products are particularly susceptible to color transfer, so care must be taken during the first few uses. It is important to avoid contact with brightly colored clothing and furniture, and if it gets wet from rain or sweat, dry it quickly. When drying leather products, avoid direct sunlight and heaters, and allow natural airflow to dry. This allows for quick drying while minimizing damage to the leather.
Avoid friction with existing clothing and furniture
When using leather products, be careful of color transfer due to friction with other clothing or furniture. Especially if you're pairing your new leather bag or shoes with brightly colored clothing, it's a good idea to take precautions to avoid chafing. For example, placing a scarf between your bag and clothing is effective.
Avoid moisture and store properly
Moisture is a major factor that promotes color transfer on leather products. When storing leather products, choose a location with low humidity and good ventilation, and if possible, use a desiccant such as silica gel to reduce moisture. You can also protect your leather products from dust and direct friction by using a storage bag or box specifically designed for them.
By implementing these measures, you can significantly reduce the risk of color transfer on leather products. Daily care and proper storage are the keys to keeping your leather products looking beautiful for a long time.
3. How to care for leather products to prevent color transfer
Proper care is essential to keep leather products beautiful and long-lasting. Preventing color transfer is an important part of this. Below, we will specifically introduce how to care for leather products to prevent color transfer.
Using cleaners and conditioners specifically designed for leather products
Keeping leather products clean is very important to prevent color transfer. Use a commercially available leather cleaner regularly to gently remove dirt and excess dye from the surface. After cleaning, apply a thin, even layer of conditioner made specifically for leather products to help fix the dye while keeping the leather supple. This reduces the risk of discoloration of the leather itself and color transfer to other objects.
Appropriate use of waterproofing spray
By applying waterproof spray to leather products, it is possible to prevent color transfer due to water and moisture. However, not all leather products are suitable for waterproofing, so always test on a small area and follow the product instructions before use. Waterproofing spray is effective when applied before going out on a rainy day or before using new leather products for the first time.
Keep leather supple with regular moisturization
When leather dries, it becomes hard and the color transfer is more likely to occur due to friction. Regular use of a leather moisturizer or conditioner will help maintain leather flexibility and prevent color transfer. Moisturizing is important not only to extend the lifespan of leather products, but also to maintain their beautiful appearance.
Practice proper storage methods
It is important to store leather products properly even when not in use. Store in a well-ventilated place away from direct sunlight, high temperature and humidity. Also, avoid direct contact between leather products to reduce the risk of color transfer. By putting it in a leather bag, you can protect it from dust and scratches.
By practicing these care methods, you can greatly prevent color transfer on leather products and maintain the beauty and functionality of your products for a long time. Think of regular care as an investment for a long-term relationship with your leather product, and treat it with love.
Summary
Color transfer on leather products may occur due to the characteristics of the leather and dye, friction, etc. However, with proper measures and care, color transfer can be prevented.
You can prevent color transfer on leather products by taking measures such as avoiding friction with new or existing clothing or furniture, and avoiding moisture. You can also maintain the beauty of your leather for a long time by using cleaners and conditioners made specifically for leather products.
Leather products have a sense of luxury and durability, and are popular as fashionable items. In order to use your leather products for a long time, take measures to prevent color transfer and take proper care of them.

Realized with COWMONO
"Even if the price is low, we don't compromise on quality."

1. Thoroughly eliminate intermediate costs
Compared to the general distribution process of "factory -> trading company -> manufacturer -> wholesaler/retailer -> consumer", COWMONO has a direct connection from "factory to consumer".


Direct sales model completely eliminates extra costs. However, there are some challenges with shipping directly from the factory.
Issues with factory direct shipping
- Length of delivery period
- Confused about unfamiliar packaging

*Image of home delivery plastic bag
However, we do not compromise on quality.
Many luxury brands are particular about their packaging and pass those costs on to consumers.
However, COWMONO pursues ``providing high-quality products at amazing prices.''
2. Reduction of web operation costs
Many online retailers spend a large amount of money on EC site management and SEO consulting.
However, COWMONO operates without any of these costs.
3. Original sales on your own website
We sell only on our own site, not on major platforms, and avoid unnecessary fees.
4. Careful selection of products
By handling only carefully selected products, we reduce costs while maintaining our commitment to quality.
