A cool wallet! This killer duct tape wallet has a classic bi-fold design (hence the name) with nickel plated grommets. It holds all your green and some cards. During a 400ft bungee jump in New Zealand, we decided to either stop jumping off bridges or own a wallet we could be proud of. The result was our first duct tape wallet... unfortunately we had to hand it over with our pants to a fish and chips vendor in Auckland (OK, so sticky side out wasn't such a good idea). But, back at our research lab (kitchen table) after many hours of work, and the loss of our fingerprints.... the classic was born. 4" wide by 4" tall
