Fluff your laundry and reduce drying time without perfumes, chemicals, and waste. Eco-friendly, reusable wool balls are a natural fabric softener—no more dryer sheets or liquid softeners needed. Just toss them in the dryer to save energy by shortening drying time. Each is 100% wool, about 3". Set of 6 in a cotton drawstring bag. One set will last almost forever. Handmade in Nepal. Tip: Use 3 or all 6 dryer balls at a time.
