Started by struggling New York artist Terrence Kelleman, DYNOMIGHTY was the way he pursued art without having to live off dollar slices interminably. Made with a single sheet of this amazing synthetic material called Tyvek, these wallets feel like paper, but are waterproof and tear-resistant. I.e. They’re bloody cool. They're not however theft or bullet proof, so... keep properly la. They also come in various eye-catching and clever patterns. And now we have them in a range of card, tablet, and laptop cases too.
