These were originally attached to Suntory Coffee Boss. It's the Star Alliance Collection, the world's largest airline network. (They run like Choro-Q.) - South African Airways - ANA - Air New Zealand - Size (approx.) = 5.5cm x 5cm - Unused. A magnet is built into the underside of the aircraft. Pull the aircraft back to wind the spring, and when set parallel to a can (steel can), it will run around the can. It will not run on an aluminum can. Thank you. #Aircraft #Airplane #ChoroQ
