Decrease dry time and reduce static cling naturally, with sustainable sheep's wool dryer balls. Sourced directly from a family farm in the USA that uses regenerative agriculture practices. Fragrance-Free ∙ Dye-free ∙ Perfume-Free ∙ Hormone disruptor-free ∙ Carcinogen-Free — and simply Worry Free. Using dryer balls is easy | Simply throw 1 ball in for small loads and 3 balls in for a large load. As they tumble around, the wool balls keep your laundry separated. This reduces drying time, decreases static cling, and helps collect more lint. Wool is dense and works well on heavy fabrics because of its texture and strength. Wool dryer balls should last up to 5 years. Scenting | Add a few drops of essential oil to your dryer balls for a faint lingering smell on your fresh laundry. The amount of drops depends on your desired scent strength. https://rusticstrength.com/blogs/tips-tricks/wool-vs-alpaca-dryer-balls-what-s-the-difference
