keychain, is made of leather, which can be divided into genuine leather keychain and artificial leather keyring. Leather can be divided into first layer leather and second layer leather, most of our key rings are made of the second layer leather. Artificial leather is divided into recycled leather, PU leather and so on. The key chains are mostly in PU artificial leather, so we call them PU leather keychain. Then how to distinguish them? Mainly need to look at the non-woven fabrics, if there has non-woven fabrics, then it is artificial leather keyring.
