100% domestic wool dryer balls made in Maine. Toss a LooHoo dryer ball into your dryer to naturally soften your clothes. Wet a dryer ball 10 minutes before the end of the cycle and toss back into dryer to reduce static. Add a few drops of your favorite essential oil to your dryer ball to add scent to your fresh laundry. These dryer balls will last for hundreds of loads. They will start to wear down after constant use but are still functional.
