Wool dryer balls are re-usable and free of chemicals. They soften fabrics, speed up drying time and reduce static. The dryer balls are unscented but can be used with our natural scent sprays or your favourite essential oils to leave your laundry subtly scented. Order includes one dryer ball, recommended two to three per load. Wool felted by hand in Mahone Bay, Nova Scotia or Norfolk County, Ontario.
