This is a precision metal top that spins for a surprisingly long time. Most nice metal tops out there spin for six minutes or less. This well engineered design is so well balanced that it can spin for 10+ minutes. It has an aluminum core and a brass outer body so it's high quality that will last. The knurled upper portion of the top makes it easy to grip and spin. It's a great desk top toy that fits in your pocket. You can spin it on any smooth surface.
However, if you spin it on a smooth concave surface it will spin longer. I do offer a glass concave base that measures 3 inches across. When you buy the top and base together you save a little money.
