Ideal for wallet minimalists, the ultra-thin Mini Skinny card wallet from Big Skinny holds up to 12 full-size plastic cards. It's great for joggers, slipping into tight pants and sliding into small purses. The Mini Skinny features three credit card pockets, a storage pocket and an 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 Mini Skinny wallet measures 4-1/8 x 3-1/4 Inch (and 2 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.
