By working to separate laundry and keep air flow circulating, these dryer balls reduce drying time by up to 30%. This makes your drying cycle more efficient, which helps to lower energy consumption and costs. It's important to us that a conscious choice is made to look for ways to use something again &Again. This doesn't just apply to the products we make but also extends to the packaging we use. This product comes with a swing tag, with clever perforated sections and an easy peel label to remove product-specific information, leaving you with a blank tag and string to use another time.
