Rethink the way you carry with the Machine Era Wallet ($28-$45). Machined from a solid piece of metal — either aluminum or brass — they keep all your stuff in place with an elastic band. At just a quarter inch of thickness, they barely make a dent in your pocket (but, don't think that means they sacrifice durability). The aluminum wallet comes in a flat black finish, and is the cheaper and lighter of the two. The brass wallet is heavier, and comes unfinished, allowing the metal to age to a nice patina. Both are manufactured right here in the USA.
