Having cash is a concept almost completely alien to me, but I own several maxed-out credit cards that could find a very happy home in these new wallets. The name, Tyvek, actually refers to the material they’re made from, rather than the name of the company that makes these funky designs. Obviously the folded dot matrix printer wallet is a favourite, but I won’t hold it against you if you’re a bigger fan of the other finishes present.
Incidentally, Tyvek is a very thin material that’s something of a cross between paper, film and fabric, and claims to be very hard-wearing, flexible and breathable. Sounds like the future of paper money storage to me.
Available from firebox.com for a startlingly reasonable GBP£13.
