Our Scented Wool Dryerballs act as a soft, silent, natural fabric softener that lift and separate clothes, cutting down on both static and drying time. As well, we've injected these Dryerballs with 100% pure essential oils to add a hint of scent to your clothes. Dryerballs are safe for all dryer-safe fabrics. Available in a single pack. Scent lasts approximately 50 drying loads. Lavender scent.
