1. Touch by hand
That is, if you touch the leather surface with your hand, if it feels smooth, soft, plump, and elastic, it is real leather; while the surface of general artificial synthetic leather is astringent, rigid, and has poor flexibility. Press the leather surface with your fingers, there is no obvious pore wrinkles, if there are wrinkles after pressing, they will not disappear obviously and naturally.
The real leather surface has clearer pores and patterns, yellow leather has relatively well-proportioned fine pores, yak leather has thicker and sparse pores, and goat leather has scaly pores. Whether the leather surface has pores or not, this is an important feature to identify the genuine leather.
All genuine leather has the smell of leather; and artificial leather has a strong irritating smell of plastic.
Tear off a little fiber from the back of real leather and artificial leather. After lighting, all that emits a pungent odor and lumps are artificial leather; all that emits a hair odor without hard lumps is genuine leather. Cut off the corners and burn, smelly, but not the burnt smell of hair.
