100% alpaca fleece dryer balls from the alpacas on our farm! Helps cut down on dry time and use of chemical fabric softeners. These are in the alpacas' natural colors---no dyes added. A set of these should last several years, and essential oils may be used on them to impart a nice scent to your laundry. Comes as a set of 3. Each dryer ball is different, and size varies from roughly tennis ball to baseball size.
