The Spintastics Trompo Grande was designed by world champion Dale Oliver. This Spintop, or AKA Trompo, is intended for beginner to pro tricks. It features a ball-bearing tip that is made of break-resistant components and a high-quality polycarbonate plastic within the body. The size and weight of these spintops make them smooth, enjoyable, and very durable! We opted-in for rim weight distribution for extra-long spin times. It is definitely one of the best spin tops on the market.
