Firetoys Glow Juggling Ball Set - 3X Strobe LED Juggling Balls Bag This set of three juggling balls also includes a handy Firetoys (TM) carry bag. The Firetoys 70mm Glow Balls look great and feel fantastic. The light from the single high powered LED is evenly diffused throughout this stage ball. These strobing balls flash at a high frequency so they leave light trails in the dark. The switch on these balls is robust and the LED is fully protected by the ball's body making these glow balls very durable. Simply twist the switch to turn the balls on or off. Each glow ball comes supplied with a full set of 3 x LR44 batteries. On a fresh set of batteries, these balls will run for 2-3 hours solid! Each ball weighs about 155g. Please note: these balls may be supplied with plastic spacers between the batteries to stop them discharging. Just open the ball, remove the batteries and take the spacers out and you're ready to go!
