They were found on the arms of a statue in an ancient building. Jackie simply wanted them as a discovery for the museum, while Hak Foo initially refused to state why he wanted them. Jackie got away, but Hak Foo soon followed him to Uncle's shop. When they were both accidentally shrunk by Jade's spell, the armbands shrunk with them. Hak Foo managed to take the armbands, and by wearing them, he grew two new arms, each just as nimble and muscular as his original ones. After Hak Foo returned to his normal size, it is unknown what happened to the armbands.
