Nellie's Dryer Balls are designed to reduce drying time and soften fabrics naturally without using chemical fabric softeners. As Nellie's Dryer Balls tumble around in the dryer they lift and separate fabrics allowing air to flow more efficiently thus reducing drying time up to 25%. Saves time & money! The unique design of the Dryer Balls nodules relaxes the fibers during the drying cycle. Clothes feel softer and towels are more absorbent. 10 minutes on medium heat will push wrinkles right out, which means less ironing! These dryer balls are non-toxic, recyclable & come with an all-new fragrance option.
