The item is a ping pong robot it has electric motor. It was rejected because it was deemed to have magnetic substance.
Is there no chance of getting it shipped?
One of my friends is coming by air China flight, can he bring it along with him? Or he can't check in magnetic devices as checked in baggage on air China flights as well?
