Alpaca fiber felted into sturdy dryer balls that last for years. Dryer balls can be added to your dryer load to speed up drying and separate clothing during drying to create even drying which decreases static build up. Static is caused by excess drying so make sure to adjust your settings to use less energy and save money. Dryer balls eliminate the need to buy dryer sheets. If you are looking for a fresh scent simply add a few drops of essential oil or skin safe fragrance oil to your dryer balls before starting each load. I recommend using 3 for normal sized loads. I use 5-6 for blankets/dog beds/heavy loads. Dryer balls weight around 3.0oz. Natural colors could include solid or mixed colors. Colors include black, gray, white, tan/fawn, and brown in a variety of shades. Dyed colors could include natural colors but will also include hand dyed colors.
