There are plenty of wallets constructed from recyclable materials out there, and in some cases they've become quite the cult fashion accessory.
With such modern styling, however, there aren't many ethically-produced wallets rocking the old-fashioned leather look many folk associate with the item.
My Old Wallet has solved that aesthetic anomaly with this version of its popular Mighty Wallet (above, click image to enlarge). While you can still go for the kitsch comic book design, or the Air Mail version which allows you to appear well-travelled, this rugged design is perhaps more suited to the debonair (but environmentally conscious) gentleman.
Like all Mighty Wallets it's still made from 25% recycled materials, and can itself be recycled after you've spent all your money and maxed out your cards.
