I duct taped my fender when it got crunched by a drunk lady. I duct taped my shoe when it came apart and I had to walk in the snow. I even duct taped my screen door at the hinges when it dangled and wouldn’t close right.
So it makes perfect sense that a duct tape wallet would be the coolest and toughest thing ever. I think it looks sleek. Remember, duct tape is the new titanium.
