C'mon leather...put up your dukes. Simple, black and thin. The discreet look of a traditional black leather wallet has been upgraded with the super thin and ecological Mighty Wallet design. The Mighty Wallet® is tear-resistant, water-resistant, expandable and recyclable. Made from Tyvek® (think express mail envelopes), the wallet resists tearing because of thousands of interlocking plastic fibers spun in random patterns giving the wallet incredible strength. The ingenious origami construction was and is the original folded Tyvek® wallet designed by Terrence Kelleman. The stitch less design reinforces the materials own strength and allows the wallet to instantly expand and adapt to your own personal storage needs. The Mighty Wallet® will expand right before your eyes (watch the video). Because of the slim, lightweight and water resistant features, you can take your Mighty Wallet® anywhere. It makes a great "night out" wallet for a slender silhouette and the writable surface conveniently acts as a quick note pad on the go. In time, the Mighty Wallet® will gradually soften and patina but, even after years of wear, it will still offer surprise and solicit intrigue.
