So slim you'll forget it's there! (Seriously, its as tall as two pennies. If even.) Full grain leather, original design. Handmade by designer Damien Mitchell in Baton Rouge LA. The notches provide easy access to the cards and cash you *actually* use, and the minimal design slides effortlessly into front or back pockets. Ditch the bulk and get going. Leather will gain personality and patina with age.
