The Helo spinner set includes the hand held stress reliever and a stock design or customized box. The spinner rotates at high speeds when held and spun between your thumb and middle finger. This fun tool fights boredom and features a central precision bearing that produces a smooth spinning action of over 2 minutes. The slight indent on the finger surface keeps the spinner in place. You can customize your Helo spinner set by mixing or matching the body, center button color and box color. CPSIA compliant for ages 5+.
