**DRYER BALLS SOLD SEPARATELY** This is a great way to add scent to your laundry or refresh your potpourri! Choose a 1oz., 2oz., 4oz. dropper bottle to easily refresh your wool dryer balls. --->>> THESE ARE NOT TO BE USED AS ESSENTIAL OILS AND NOT TO BE USED AN ELECTRIC DIFFUSER OR TO BE SPRAYED IN THE AIR. --->>> WASH WITH SOAP AND WATER IF YOU GET THE OIL ON YOUR SKIN. --->PLEASE NOTE... all oils are not the same weight and have different density. That means that when we weight out your oil, you are receiving the amount you paid for (1 fl oz, 2 fl oz, 4 fl oz or 10 fl oz) per the weight of the oil. When a oil is heavier, it's not going to fill the bottle completely like a lighter weight oil would.
