YoYoFactory Velocity is THE yo-yo of the 21st century: the Velocity is the first yo-yo of its kind. With the adjust-o-matic dials on each side of the yo-yo, the Velocity can be turned from a classic up and down yo-yo into a modern bind-return yo-yo with the turn of a dial. With the dials turned down for classic performance, you can throw the yo-yo and tug it back to your hand with ease, which makes it easier to learn the basics of yo-yoing. With the dials turned all the way up, the Velocity is capable of doing the most difficult tricks you can throw at it. Product Measures: Width: 37mm / Diameter: 55mm Recommended Ages: 8 years & Up. Colors vary.
