Nellie's Dryer Balls, PVC-FREEProduct Rating: Product Review (submitted on July 1, 2010):
These dryer balls definitely help to cut down on drying time and make my clothes soft and fluffy! I LOVE that they are PVC-free.
My only warning would be to not use them with PUL diapers or wet bags, as I have found they stick to the PUL! They could potentially cause extra wear or damage.
