1. First, check whether there are pores on the leather surface. Cowhide has fine pores, irregular arrangement and smooth leather; Pores of pigskin are arranged in a triangle, and the cortex is loose.

2. Then, when checking, you can use the indentation to see if there are any fine lines scattered in the indentation.

3. Second, check the edge of the cortex. The dermis is loose and the fake skin is tight.

4. Genuine leather and fake skin can also be distinguished by smell. Leather obviously has an animal smell, while artificial leather is relatively more inclined to stimulate the taste.

5. Trademarks and meticulous workmanship.
