It's super thin. It's super lightweight. It's the Big Skinny credit card holder. Or, shop our equally super thin credit card cases and wallets for men and women. Our small credit card wallets and cases are only slightly larger in size than a credit card, but they can hold plenty of cards and cash. That's because they're made with our proprietary nylon microfiber, which very thin, very light and very tough. If you drop your small credit card case in the mud, it will handily survive the washing machine.
