How to write the slogan of selling cowhide wallets in online stores?

According to the requirements of the State Light Industry Bureau [1], the new industry logo was implemented on April 6, 20 1. The identification document number is QB/T 1333-20 10 (handbag), QB/T265438. The logo changes as follows:

1, the first layer of cowhide and the first layer of patent leather were changed to cowhide.

2. The second layer of leather was replaced by artificial leather made of cowhide fiber.

3. PVC changed into artificial leather.

4. Interlining cloth (including nylon cloth and cotton cloth) is changed into fabric.

5. Change fabrics (including cloth and nylon) into fabrics.

According to this standard, the first layer of leather should be cowhide and the second layer can only be regarded as artificial leather.

Cowhide is real cowhide and will never peel off after use.

The second layer of leather is artificial leather. After use, it will fall off.
