This unbelievable wheel is the only wheel with sparkles (thanks to the flints inside of the wheel) AND with LEDs. You certainly will be the center of attention with eight wheels of them!
The classical spacers are replaced with a “magnetic” spacer, which is the reason that the wheels shine. (These special spacers are included).
(Of course you still need bearings, like all the other wheels.)
You will be amazed about the strong grip of the wheels for the 88A durometer, and about the speed, which is very high for a wheel with sparkles and LEDs.
