Dirty Labs Wool Dryer Balls are a sustainable alternative to traditional dryer sheets and fabric softeners. By fluffing and separating laundry as it tumbles, our Wool Dryer Balls allow air to circulate more evenly, reducing drying time, static, and wrinkles. Responsibly sourced and made from 100% New Zealand wool, Dirty Labs Wool Dryer Balls are nontoxic, biodegradable, and free of added dyes, fragrances, and chemicals. * Freshens and softens fabrics * Dye and fragrance free * Responsible RWS Certified Wool
