Wool Dryer Balls work by bouncing around in your dryer, lifting & separating clothing, & increasing the hot airflow. They cut down drying time by 25-35% which saves you money on energy costs! Contact us for custom logo tags in a cotton drawstring bag and pricing! Instructions for Use: Place wool dryer balls in the dryer with your laundry. For EXTRA freshness add a couple of drops of your favorite essential oils! Why are wool dryer balls better than fabric sheets? Fabric sheets use harsh chemicals to soften clothing which is toxic to the environment. Wool dryer balls are a nature-friendly alternative. Our dryer balls are handmade with 100% New Zealand wool. Made in Nepal by women and minorities paid a living wage.
