We can't think of any better advertising for our curved bi-fold wallets at Big Skinny than the more than 100 five-star reviews from our customers. The words "great" and "love" are used the most. This fun, uber-functional nylon wallet has two curved edges to easily slip into a man's front or back pocket. It's that extra way to hold your cash and card stash for women's pockets and purses, too. This lightweight little wallet with two rounded edges has extra-wide pockets inside to hold up to 20 plastic cards, plus cash and other essentials. Each of the bi-folds pockets and the billfold area are lined with a grippy coating for a non-slip finish that will prevent your cash and cards from falling out. The wallet is made of machine washable nylon microfiber that's also sturdier than most ordinary wallet materials. Watch our video on how much you can load into this extraordinary compact wallet. It's 4 5/5 inches by 3 1/8 inches in size and only one-eighth of an inch thick when closed.
