Clear Longboard/Skateboard, Jellyfish 40" Platypus, Yellow Trucks, and Purple Light Up Wheels. We use high-quality wheels meant for speed and carving. Our wheels are made from a polyurethane formula. The wheels are clear with led lights in the middle that light up and glow when spun. The led lights are powered by a magnet using friction from the spinning wheel to light up. The wheels are 70mm in size and have 78a hardness with abec-7 bearings. These boards aren't slippery and don't need grip tape at all. Clear grip tape ruins the see-through look of our boards. We found that our boards are even grippier when you drip water droplets on them! To keep your board nice and clean use soapy water and a microfiber towel for best results.
