Clover's Yarn Ball Winder can wind more yarn with fewer handle rotations, because of our unique internal gear system. It is designed with a protective cover and an inner lid to prevent yarn from becoming tangled and lint from entering while you wind yarn. The optimizied distance between the yarn guide and bobbin allows you to easily wind up to 3.5 ounces of yarn. The long handle shape makes it easy to turn and reduces fatigue. It is manufactured and assembled in Japan to offer consisitent functionality and a smooth winding feel. Stable winding, superior design and easy to use.
