These LED Balls use the G-Light system, these are LED units that can be easily removed and used with other juggling props. 

The G-Light units are transferable between and usable with the G-Light soft juggling ball shells, acrylic contact shells, poi shells and juggling clubs! This means that you don't need to spend a fortune to get a fantastic range of LED juggling equipment. The light units can be easily swapped between props so you'll only need to buy one set of LED units to use with any G-Light prop.

Price is for one 80mm ball shell, this does not include the G-Light LED unit.
