The C-Car Keychain. $5.98. Suddenly the awesome and unbridgeable gap between life in the US and that in Europe stares us in the face like a wounded buffalo. We live in separate universes!
Don’t be embarrassed to admit that you lost your car in the parking lot — you aren’t alone! Just ask that guy wandering next to you! But now there’s a solution — the C-Car keychain. Simply point the keychain toward the store from your car and line up the rotating car logo. When you leave the store, hold it horizontally (like a compass) until the car logo lines up again–and head toward your car! No batteries required
So it’s a compass then.
Actually I don’t think it is. I think it’s a little bit of plastic with a manual rotary dial on it with an arrow.
