Most wallets just keep stacking cards on top of cards. This thin wallet design cuts them in half just like one cuts a deck of cards. The Super Skinny ends up being 1/2 as thin as even our other designs and 4 times thinner than a typical leather wallet with the same amount of cards and cash. The math is pretty good eh? Not bad, especially since all the extra-wide pockets can fit a total of 30-36 full-size plastic cards and you still have the billfold area for cash, receipts, etc. The pockets and billfold area are lined with a rubbery coating to help prevent cards and cash from sliding out. This model also has a horizontal-style card layout to additionally prevent cards from sliding out. The first pocket is stretch elastic to keep extra secure. Wow! Now that’s sleek, slim, and light. And flexible---designed with “joints” so the sections move & bend along with your body for more comfort despite its larger size. And this super slim wallet still fits in typical male pockets smoothly.
