Identification of authenticity and observation materials for leather bags

When identifying, the material should be checked first to determine the type of leather. If using an unmodified "genuine leather" grain surface layer with natural characteristics:
Cowhide pores and small, irregular and relatively uniform eyelets; The goat's fur eyelets are arranged in rows in a tile shape; Pig skin with three holes and a pile, distributed in a character pattern; Yellow cowhide tissue has fine fibers; Buffalo leather is rough and has large pores. For particles that have lost their original characteristics after modification, they should be carefully classified and identified according to the processing technology.
