Unless you have enough money to convert it to gold doubloons and swim in it, the way you carry your stash says just as much about it as its size. If you want to project copy room, go with a paperclip or a rubber band. If you want to project board room, go with something like Hard Graft’s new Nero Card Case. Made from wool and semi-vegetable tanned leather, the Nero is as simple as it is sleek. In case the single slot card case gets a little too packed with your benjamins, there’s an optional elastic strap to keep everything under control.
