OLSEN+OLSEN dryer balls are handmade with wool. They soften your laundry naturally without any of the chemicals of conventional fabric softeners. Unlike the plastic dryer balls, they are PVC free and won’t fall apart or melt on you. Our dryer balls save time and energy by cutting down on drying time by an average of 25% per load. They also help reduce static and wrinkles. You can choose white balls, grey balls or a mix of both colors. Dimensions: 7 cm diameter each ball / 4g each Informations about the product: Add a few drops of our essential oil and throw them in your dryer. That way you will ensure that your clothes smells fresh and that you avoid static electricity. OLSEN+OLSEN balls are made of natural materials. Why use plastic when you can use a naturally source product that will eventually decompose after their 1000 loads.
