It is now possible to carry all of your cash, identification cards and credit cards safely and comfortably in your pants, shirt or jacket pocket with a Big Skinny flat bill wallet. These revolutionary wallets are constructed from extremely thin and very durable nylon microfiber material. They have a special design that includes several different inside pockets so you can separate your cards, giving you a large capacity wallet that is 50-75 percent thinner than ordinary wallets. Because it is so thin, the wallet will sit flat, even when filled with cards and bills. The absence of an ugly bulge gives you a cleaner, more stylish look. This very light and flat bill wallet is also good for your health, because you aren't carrying around the extra weight in your pocket. Professional websites specializing in spinal health will tell you that sitting on a bulky wallet can put additional strain on your back.
