Pure Wool (100%).
Simply toss the 3 balls into the dryer to create loft while dryer tumbles. Reduces drying time, wrinkles and static without the harsh chemicals of conventional fabric softeners. Care: Pilling may occur over time. You can remove pills but they actually aid in the process. To refresh Woolzies static reduction quality, place each Woolzies Dryer Ball in a thin sock and run through a hot wash cycle with detergent. Remove from sock and place in dryer on highest heat setting.
