Cons
Con The edges bend

Con Logo tag
Some wallets have a rubber logo sewn onto the outside front. Because it is thicker than the wallet material, it can catch slightly when transferring the wallet in and out of a tight pocket. It's worth mentioning, even though it hasn't really been a problem for the many years I've had my wallet. Also, the logo is a handy way to mark the front corner, for easy orientation of the wallet when swiping RFID cards.
