I put a few drops of my favorite oils and they work wonderfully! Never smiled doing laundry before!
Love my buzz trio dryer balls. Helps eliminate static and reduces need for costly dryer sheets.
We use the dryer balls for juggling, throwing at each other, hide-n-seek and the purpose they were intended for. They work awesome to keep clothes light and fluffy when drying and are so cute to look at every time I open my dryer.
