I accidentally stumbled across this wallet and I liked the idea. I didn't care about Tyvek nor did I cared how thin it was. I fell in love with number π (pi) on Dot matrix printer style paper.
I shared my excitement with wife and she immediately noticed that you don't have pocket for coins. Disappointed with this, I decided not to buy it. That decision didn't last too long since I did order it next day.
I have wallet for more than a month now and I cannot say that it is most practical wallet I had. I keep my coins floating freely in my pants (no pocket for coins), least used cards are hard to extract from wallet (only two compartments) and my driver's license cannot fit.
However, every time I take it out and I see those numbers, I do not care. This is ultimate wallet that programmer can have.

Hi Medo – Thanks for posting about our Mighty Wallet. I designed the Mighty Wallet from a single sheet of Tyvek because one of my biggest problems with traditional wallets is they always seem to tear where they are stitched. This also allows the wallet to adapt to fit Whatever you put inside. I hear your concerns about the ID pocket and the coins, that is something that I’m trying to address for our European customers who have those larger value coin denominations.
I hope you still enjoy the Mighty Wallet and I welcome your feedback as you live w/ break in your Pi Mighty Wallet! Best wishes,
Terrence
I do enjoy that wallet and I am eager to see European version (as you noted – not all Euro bills do fit).
