Dry your clothes and make them wrinkle free with these spiked plastic dryer balls. These dryer balls are made from non-toxic materials that provide a natural way to dry laundry. The spiked design helps loosen and separate wet and dense loads of laundry, so they dry more thoroughly. During the drying cycle the dryer balls tumble in the drying machine softening fabrics and preventing static cling without the need of harsh chemicals. Tumbling between damp layers of wet fabric for increased air flow, the small spikes lift, separate, and fluff laundry to cut drying time by 25%. Hand wash recommended. Toss 2 for a standard load and toss 4 or more for a larger load.
