London Underground Map Mighty Wallet by Dynomighty

The official licensed map of the London Underground. The "Tube" map is based not on the geographic but the relative positions of stations along the lines. A style that has been adapted worldwide. The Mighty Wallet is tear-resistant, water-resistant, expandable and recyclable. Made from Tyvek (think express mail envelopes), these cool wallets resist tearing because of thousands of interlocking plastic fibers spun in random patterns, giving them incredible strength. The ingenious origami construction and stitch less design reinforces the materials own strength and allows these slim wallets to instantly expand and adapt. Open dimension: W: 8" H: 3.25".
