Here’s a wallet that no pickpocket would think to snatch. To the untrained eye, this is merely a wad of geek data. But open it up and inside are all the compartments of a normal billfold.
The wunderkinds at DynoMighty have a whole series of paper wallets made to look like newspapers, air mail envelopes, and other paper goods.
Each is made from Tyvek, which looks and acts like paper made from trees, but is actually a synthetic fiber created by Dupont with 10 times the strength of paper and virtually untearable by hand. Special seams allow for easy expansion. US$25 + shipping. – www.dynomighty.com
