Drying balls for drying clothes in the dryer will shorten drying time by up to 25% and reduce static charge of the laundry. The laundry is less wrinkled and most laundry does not even need to be ironed. You simply put the balls in the dryer with the laundry. The wool absorbs residual moisture, and as they move in the dryer drum, the balls separate the laundry from each other so that the hot air can circulate more effectively. They naturally soften the laundry, save time and money on energy, and when using them, you do not need to use fabric softeners, fabric softeners and scented dryer sheets. However, you can use a natural essential oil. If you drip a few drops on the balls before putting them in the dryer, your laundry will smell wonderful. After taking the laundry out of the dryer, you can leave the balls in the dryer drum with the door ajar. The balls do not make noise in the dryer, they are quiet, light, non-toxic, chemical-free, fully biodegradable, and kind to the planet. Set of 3. Material: antibacterial and antifungal sheep wool from New Zealand. Dimensions: dia. 7 cm.
