Improved crystal spike bracelet. Side by side there is no comparison; this new bracelet blows the older style most companies currently carry out of the water. All silicone spikes light up and can be seen clearly through the high quality plastic. This product is as good as it gets for LED bracelets.
Run time is 12+ hours.
One size fits all. Individually packaged. Batteries are not replaceable. Ages 8 and up.
