By now you’re probably just as sick of hearing about the Costanza wallet as we are of talking about it. Not cramming every single receipt, credit card and piece of cash you have into your wallet and leaving it there is easier said than done a lot of times. If you’re going to slim down your wallet to the bare necessities you need a reason to do it. Back problems are a good one, but these Southern Field Industries Flap Wallets are better. Made of Japanese vegetable tanned cow leather and hand sewn with sinew thread by the founder himself, each wallet is a blank canvas waiting for your imprint. It’s design and quality that will last a lifetime and not something you’ll find in a big box store.
