A compact utility pack to hold all your essentials, the Big Skinny Little Book Of Cards wallet can accommodate over 20 cards and cash. It features 20 clear plastic pockets, one interior ID pocket with a clear window that can hold up to five plastic cards and an interior pocket that can store folded cash, photos, or more cards. The extra-wide pockets are lined with a rubbery coating to prevent cards from slipping out. A snap closure keeps your items secure. Designed with rounded corners for comfort, it's constructed of a lightweight, water resistant nylon microfiber material that is 5 to 7 times thinner and lighter than leather. It's machine washable for easy care and it dries out in about 20 minutes. The Little Book Of Cards wallet measures 3 x 4-5/16 Inch (with 2-1/2 x 4-inch plastic sleeves). The first Big Skinny wallet was designed by Kiril Stefan Alexandrov (the company's founder) because he loathed sitting on a thick, heavy leather wallet. Since creating the original Sport Wallet in 2005 using an advanced nylon micro-fiber material (5 to 7 times thinner than leather), Big Skinny has added dozens of slim wallet styles for men and women with more on the way.
