Do you have any questions that I can help you with?

Bright eye catching glow
Reviewer: Wade Francis from AustraliaGet a couple of these for the different colours. Also because once you show it off and everybody wants a turn, you'll still have one to play with ;)
They're shock resistant and glow brightly. I've used these as contact juggling balls and they work well. They're somewhat lighter than the average contact juggling ball but once you get over the initial change it's all good.
Soft rubber
Reviewer: Lysa Ringquist from United StatesThese are great, the top for the battery screws on nicely and deep and stays in place.
Unlike some of the glow hacky sack balls where the light mechanism falls out with consistent use. I purchased the rainbow colors and they are beautiful.
