The best product ideas are often the simplest. DYNOMIGHTY believes that when you’ve got a great idea, there's no need for bells and whistles. Every one of its quirky wallets is printed on a single folded sheet of DuPont Tyvek, a material used in Express Mail envelopes and housewrap. Through simplicity of materials and economy of design, DYNOMIGHTY creates a canvas for expression. Working with you, not against you, The Mighty Wallet expands with your needs, and slims down again when the time comes. The material is lightweight enough not to weigh you down, but strong enough to stand up to years of use. Pick the eco-ink printed design that you love most.
