The maple wood wallet is handcrafted out of a single piece of wood. Because of this it is extremely strong. It will not break if it’s in your back pocket and is smaller than many normal sized wallets. A leather strap is secured to the wallet and it’s finished off by a magnetic clasp that securely holds its contents in place. This wallet is ideal for credit, business, and id cards. You may even be able to fit a few dollar bills in there. We promise you wont be disappointed with the craftsmanship and quality. The Wallet can fit up to 8 credit or I.D. cards and even more business cards. Our wood wallets are made in the U.S.A!
