The metal parts of the wallet, such as pull rings, buttons, key hooks, etc., must be checked to see whether the gold-plated parts are intact. Generally speaking, copper products are less likely to rust and fade. Pay attention to whether the seams of the wallet are tight. However, if they are too tight, the entire leather will be pulled too tight, causing the wallet to crack. Pay attention to whether there are too many seams on the leather surface. If there are too many seams, it means that it is made of different pieces of leather. Therefore, a good purse should avoid too many seams.
