Mighty Wallets- in the new MTA Subway map design. Made from Tyveck, these babies are tear- resistant, Water- resistant, expandable and recyclable. The ingenious origami design reinforces the durability of the material which resists tears by the thousands of interlocking plastic fibers spun in random patterns to give the wallet its strength. Features: 2 interior pockets, 2 interior facing credit card pockets (holds approximately 16 cards), and 2 quick access business card pockets. Grows to be Mighty, Mightier, and Mightiest depending on how much you "stuff" in it (George Castanza style).
