Wool dryer balls set reduces drying time, softens fabric, and controls static. These reusable, all-natural dryer balls replace wasteful dryer sheets and liquid fabric softeners. As they tumble in the dryer, the wool fibers gently massage fabrics, lifting and separating clothes to allow hot air to circulate more efficiently. This decreases drying time, saving energy and money. The wool also naturally softens fabrics and reduces static cling, leaving clothes feeling fresh and comfortable against the skin.
