This is a set of 4 spark wheels specifically for inline skating. These are the ultimate wheels that emit LED lights while skating and also scatter sparks! [Sparking Wheels] The entire surface of the light-up wheels is evenly embedded with flints, designed to not only illuminate the wheels while in motion but also to scatter sparks. The glowing wheels will race like a comet, scattering sparks. [The Secret of the Spark Mechanism] A large number of 104 flints are embedded in the wheels. The flints on the wheels strongly rub against the ground, creating a powerful display of sparks. Performing tricks like slides, drifts, jumps, and high-speed quick turns will dramatically increase the impact when you create sparks. The more and longer you rub the wheels, the bigger and longer the sparks will fly. Because of the large number of flints, you'll get a considerable amount of sparks just from normal skating. These are handmade by spark wheel artisans, each one carefully crafted with care. Quantities are limited, so please purchase them as soon as possible. The artisans make them while checking the quality.
