Meet Supr Slim, it's like the MacBook Air of wallets
Slim - The Thinnest Wallet Ever. from Supr Good Co. on Vimeo.
It is a simple concept, really. An elastic wallet just for credit, debit and coupon cards that can take as few as 2 and as many as 10 cards and still stay unobtrusive. The Supr Slim wallet is designed by the Melander brothers on Kickstarter yielding around $204,000 in pledges so a lot of people are into this idea.
