Frequently Asked Questions
What is a Mighty Wallet made of?
Tyvek, the same tear-resistant material used in express mail envelopes. Thousands of interlocking plastic fibers make it nearly impossible to rip while staying featherlight, water-resistant, and recyclable.
Who invented the Mighty Wallet?
Brooklyn artist Terrence Kelleman, who founded Dynomighty and created the original folded Tyvek wallet in 2005. Its stitchless origami construction has been widely imitated since.
How long does a Tyvek wallet last?
Longer than you'd expect for the price. The material resists tearing and water, and the folded construction has no stitching to fail. The wallet also expands to fit what you carry.
Can you customize a Mighty Wallet?
Yes. Dynomighty prints designs in Brooklyn and has offered custom printing alongside licensed designs from partners like DC Comics, Marvel, Sanrio, the USPS, and MoMA.
