Dynomighty "My Old Wallet"

The Mighty Wallet is tear-resistant, water-resistant, expandable and recyclable. Made from Tyvek (think express mail envelopes), the Mighty Wallet resists tearing because of thousands of interlocking plastic fibers spun in random patterns giving the wallet incredible strength. The ingenious origami design reinforces that strength by using a single folded stitch less construction allowing the wallet to gradually expand and adapt to meet your own personal storage needs.
