The same great Mondial Injection yo-yo, with the Duncan name proudly on it! The Mondial is an aluminum nonslip twist-adjustable ball-bearing transaxle yo-yo with raised positive grip. It comes with rubber o-rings on the outside edge to protect your hand. It is an amazing piece of engineering and machining. The gap-adjustment system is indexed, clicking and locking into place so as not to slip, every .023mm (half the width of a human hair). It has over 50 position settings. It has an internal reservoir to "inject" lubricant directly into the yo-yo. Your Duncan Mondial will come pre-lubricated and ready to play.
