Wool Dryer Balls by Plant Therapy naturally softens and reduces static. This six-pack of reusable dryer balls are crafted from 100% New Zealand wool. They help separate clothes and improve air circulation, decreasing drying time. These eco-friendly, chemical-free dryer balls are a reusable alternative to single-use dryer sheets, with each ball lasting up to 1,000 loads. While they don't add any scent on their own, they can be combined with laundry blends for a light fragrance.
