Wool dryer balls make your tumble-dryer work smarter, not harder. They bounce around in the dryer, creating space between your clothes, towels or linens. The hot air moves around more efficiently, so your laundry dries up to 50% faster. Wool Dryer Balls also work as a natural fabric softener, reducing static and the need for synthetic chemical softener. TO USE: Toss a ball in between handfuls of wet laundry. Try not to overstuff your dryer to allow room for your dryer balls to bounce freely. For freshly scented laundry, add a few drops of our Fragrance Oil at the end of your dryer cycle and run on low/mo heat for 10 minutes.
