The side-by-side stacking solution of our Super Skinny creates a flat, flexible plane for your wallet - now with RFID blocking technology to keep your data secure! 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 playing cards. So this thin wallet will be half as thin as even our other designs and four times thinner than a typical leather wallet with the same amount of cards and cash. The wallet math is pretty good eh? Not bad, especially since all the extra-wide pockets can fit a total of 35-40 full-size plastic cards and you still have the billfold area for cash, receipts, etc., and whatever else you choose to put into the hidden pocket. Now that’s sleek. Slim and light. And flexible--designed with joints so it bends whether in your back or front pocket. And this super slim wallet still fits in regulation male-sized front or back pockets smoothly.
