100% felted NZ wool - 7.5cm, 6 pack These natural woollen dryer balls will be a game-changer to your laundry routine. As they bounce around in the dryer they increase the flow of air and soak up excess moisture, cutting your drying time by up to 25%! Woollen dryer balls also naturally soften clothing, reducing the need for nasty chemical fabric softeners, their presence in the dryer reduces static and can help remove pet hair and other lint from laundry. Being wool, these dryer balls have the added bonus of quiet operation. No harsh banging, risk of damage to the dryer or transfer of toxic residues from plastic-based alternatives. Made from 100% felted wool, our dryer balls are tightly woven and will last hundreds of uses.
