Inspired by the demanding pace and size constraints of big city living, the Taxicat bi-fold wallet features plenty of card pockets, a billfold area, magnetic snap enclosure and an exterior change compartment. This wallet can hold 20 to 25 full-size plastic cards in its three card pockets, two extra-deep storage pockets and ID pocket with a clear plastic window (for easy access to your driver's license or work badge). The extra-wide pockets are lined with a rubbery coating to prevent cards from slipping out. 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 Taxicat wallet measures 4-5/8 x 3-1/8 Inch (and 5 mm thin when empty). 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.
