The Star Wars Logo Mighty Wallet is tear-resistant, water-resistant, expandable and recyclable. Made from Tyvek, this cool wallet resists tearing because of thousands of interlocking plastic fibers spun in random patterns, giving it incredible strength. The ingenious origami construction was and is the original folded Tyvek wallet designed by Terrence Kelleman. The stitchless design reinforces the materials own strength and allows these very slim wallets to instantly expand and adapt to your own personal storage needs. Ages 13 and up.
