Made from 100% New Zealand wool, these Wool Dryer Balls soften your laundry, reduce static cling, and shorten drying time... Naturally! They have absolutely no toxins, and because they reduce drying time by up to 30% and replace fabric softeners and dryer sheets, they're good for the environment, too. Use 3 or 4 balls in small or medium loads and 5 or 6 in large loads. Cruelty free and handmade with love in Nepal!
