Just bought the ALL-ETT Billfold Wallet after reading about it on Kevin Kelly’s Cool Tools (he’s a co-founder of Wired)
Cool tools really work. A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful.
The wallet is made of paper-thin ripstop fabric. There’s a shallow pocket for money, a deep one for papers, plus room to hold 20-30 cards. Even with all that, it’ll still be just 1/4″ thick or so and fit easily in a front pants pocket or shirt pocket. Quite amazing. Only $20.
I want one.
