If this isn't one of the coolest things on your desk, we will be sincerely surprised.
This VW Bulli speedometer clock just oozes cool. First, you crack the "can" lid. Then you flip a kickstand so that it will rest easily on your desk (or nightstand, coffee table, or camper table). No, it's not a real repurposed speedometer, but it sure looks like it is!
Requires one AA battery (not included). Can be wall-mounted (hardware not included).
Dimensions: 9 cm x 9 cm x 5 cm
