The laundry dries faster. The dryer continuously measures the moisture during drying and adjusts the drying time according to the dryness of the laundry, allowing for a savings of approximately 25-40% of drying time (depending on the dryer model). The dryer balls are made from 100% pure, felted sheep wool and act like a natural fabric softener. They reduce wrinkles and static cling, all without chemicals. They are particularly suitable for people with sensitive skin, allergy sufferers, and babies. They are also ideal for the care of down jackets and comforters. Special benefits include: significantly softer and cozier clothing without the use of chemicals such as fabric softeners or dryer sheets; ideal for sensitive skin; 100% natural from sheep wool; improves the wearing comfort of laundry; reduces static cling in textiles; saves energy and time; reusable indefinitely; wool dryer balls make less noise than plastic dryer balls.
