Pacific Air Clothes Dryer Balls work by separating items in your clothes dryer. This allows more air to circulate around them, which means clothes dry faster. The spikes on Clothes Dryer balls together with the rotating motion also work to naturally soften clothes, removing the need to use chemical softeners. Because clothes get separated, they also come out of the dryer with less creases and wrinkles so less ironing is required. Clothes Dryer Balls are reusable and will last for over 100 drying cycles.
