Extended data:

Broken skins are scraps of various top-grade skins, and the color of each skin will be different and will be changed when leaving the factory. Some finished products will change color and fade, and can be sprayed again (oily broken skin will change color and fade again after spraying, and non-oily broken skin will not fade with glue).

After all, it belongs to the first layer of skin and is breathable. Flexibility and service life are no different from those of high-quality leather, because the cost of breaking skin is relatively low.
