Laundry Sauce wool dryer balls naturally soften loads. These reusable dryer balls help reduce pet hair and lint clinging to clothes. Compatible with all machines, the dryer balls shorten drying time for up to 1,000 loads. The tightly compressed New Zealand wool separates fabric, allowing warm air to circulate, which helps prevent laundry from clumping. Clothes come out smelling, looking, and feeling good.
