Three Juggling Balls made from a smooth soft-to-the-touch plastic so they are comfortable to catch & pleasant to use. in addition they contain LEDs that can be set to slowly cycle or flash through a spectrum of coloured light so they will make your juggling routine even more spectacular! The operation is quite easy but a clever feature requires the switch to be depressed for several seconds before the lights switch off so there is little chance of the pretty display being dimmed during a routine.
