The spiked jelly ring is made out of a soft silicone plastic to fit any finger size. The top of it has a 5 super spikes in a star shape on it (but don't worry it's not sharp!) and an on/off button on the underside. Turn on the ring and it flashes super bright with red, yellow and blue lights. Batteries included but not replaceable.
Available in neon green, hot pink, neon yellow and blue!!
