Wallets can be basically divided into medium and long wallets and short wallets according to their styles; The middle and long wallet is long in shape and long in length. If you have more things and put your wallet in your bag, it is better to choose a medium and long bag. For short wallets, medium and long wallets are also more impressive. The short wallet is short in length and width, which is generally close to a square. If you often pack money in your pocket, it is better to use the short wallet.
