The Shalgo Duct Tape Wallet is brilliant. Urban Outfitters carries them for $20 plus $6 shipping.
A card inside the wallet says it was made by "Dutch duct tape ninjas." The colors and layout are aesthetically pleasing. Every seam is covered to minimize tackiness. The design is very clever.
It's a little expensive, but that's offset by the quality of construction. The wallet could use a few more credit card pockets, but I'm just being nitpicky.
Thank you, Dutch duct tape ninjas.
