Environmentally Friendly: Wool dryer balls are made from renewable and biodegradable materials, making them an eco-friendly choice compared to disposable dryer sheets. Cost-Effective: While they have an upfront cost, wool dryer balls are reusable for hundreds of loads, saving you money in the long run compared to single-use products. Gentle and Safe: Wool is gentle on fabrics and suitable for all types of laundry, including delicate items. They are also safe for people with sensitive skin or allergies. Reduced Wrinkles: The movement of wool dryer balls in the dryer helps to prevent clothes from clumping together, resulting in fewer wrinkles and easier ironing.
