Touch by hand If you touch the surface of the leather with your hands, it is smooth, except for the leather with a coarse grained surface. The feeling of softness, plumpness and elasticity is genuine leather. PU leather is generally dry and inelastic to the touch, and it will be soft when it is better made, but the surface gloss is oily and shiny. 2. Observation (1) The real leather is animal fur, and there will be many irregular pores and patterns on the surface, and the lines are not repeated. There will be obvious differences when pressed by hand, while the pores of PU leather after pressing are smaller, the state is uniform, and the lines are more single. (2) In addition, PU leather items have a layer of textiles as the bottom plate. This textile bottom plate is used to increase its tensile strength, while the reverse side of the leather does not have this layer of textiles. This identification is a simple and practical method for genuine leather.

Pu leather will produce a pungent smell when it is ignited, and it will form lumps after burning.

The pu leather will appear directly on the leather, which can be wiped off by hand without any change on the leather.
