I never know what to do with old bicycle inner tubes. I mean, you can only be Rambo for Halloween a couple of times before it gets old. Usually they end up in a box with CD spindles, strips of fabric, and other junk that falls under the nebulous “future art project” materials collection. Somebody should remind me that I don’t actually do art projects.

So it’s a good thing Mission Bicycle Company just got these swell mini-wallets that are made from recycled tubes. Seems like a cool idea for those of you interested in lowering your rubber footprint:

This super thin wallet is perfect for a night out or a training ride when you don’t need to carry every card you own.

• Fits in your front pocket
• Pocket for folded cash
• Pocket for credit cards
• Window for your ID

What do you do with your old tubes?
