No.11 is made for those of us who carry a bit extra, but don't want to deal with the back busting brick-of-a-wallet that we're used to. This wallet features a large pocket for carrying 6+ cards and a slot for carrying 2-3 of your most commonly used cards. Those pockets all get covered by a flap that protects them from falling out or getting damaged. On the rear of No.11 is a pocket for carrying folded cash. Your cash can be reached with the flap open or closed. This wallet is made of strong 5oz. vegetable tanned leather from the Wickett & Craig Tannery in Pennsylvania.
