【Photo on the Left】 The Ethnic King Hand Spinner delivers spinners that have passed rigorous inspections to our customers. It is formed with high-precision CNC and consists of 18 colorful O-rings, 10 CNC-machined brass parts, and one stainless steel R188 bearing, with a brass body. Average spin time: 4 minutes, up to 6 minutes. Boasts the longest spin time in the Ethnic series. It's very simple to use, just spin it with your fingers. You can play with it like pen spinning when you're thinking, stressed, or just have idle hands. It's also expected to have a stress-relieving effect.
