Big Skinny's most popular international wallet is now lined with RFID blocking technology to keep your information safe. This model accommodates international currency and features a handy exterior coin pocket. Crafted from durable, top-grain cowhide leather on the exterior and ultra-thin, lightweight nylon microfiber on the interior. Our extra wide card pockets make it convenient to store a few cards in each slot and make it easy to grab what you need. The card pockets and billfold are all lined with a non-slip interior to help prevent your goods from succumbing to gravity when you're scaling a building. An ideal wallet for travelers, the Big Skinny World bi-fold wallet features an extra-wide, extra-tall billfold area that accommodates larger international currency. It also includes zippered coin pocket on the outside for easy access. This version of the World features an exterior constructed of top grain cowhide leather and an interior made of Big Skinny's ultra-thin nylon microfiber material to help keep it thinner than a typical wallet. Almost a perfect 4 x 4-inch square, the World holds more than 30 cards yet retains its ultra-thin profile. It also features six card pockets, two extra-large hidden pockets, 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. The World wallet measures 4-1/4 x 4 inches.
