These 100% alpaca dryer balls are hand made from my own alpacas and other locally sourced alpaca fiber. They are minimally processed, using a fragrance and dye free detergent to aid the felting and clean the fiber. They can replace your chemical-laden dryer sheets and fabric softeners, while speeding the drying process and minimizing static and wrinkles. The best part about them is they magically prevent long hairs from becoming tangled in your delicate items! They are fragrance-free, but you can add a few drops of your own essential oil if you prefer fragrance.
