After learning about dryer balls, we were skeptical about what they claimed they could do. Always enjoying science, we decided to experiment and see if any of it was true. While we can't confirm that they will make your dryer more efficient or your clothes any softer, we did notice a decrease in the amount of static in the dry cloths. We had the most improvement when using DAMP balls in the dryer. Now we've tossed out the fabric softener and are happy to be using less chemicals in our laundry.
There are three 1 oz balls in each kit, made from 100% natural alpaca fiber.
