Toss them into the dryer and your clothing will dry faster, fluffier and softer, with fewer wrinkles and less static cling. 100% natural, premium wool with no synthetic fillers, rolled into tight, 2.75 inch balls and felted for a natural, long lasting product. Replace chemically infused dryer sheets and liquid fabric softeners with an eco-friendly and natural alternative that will last more than a thousand dryer loads. As the dryer balls tumble around in the dryer, they lift and separate laundry allowing the hot air to circulate better and dry faster.
