No. Our Wool Dryer Balls are completely natural hence there is no fragrance and/or scent/odor in them.

However, another neat little trick you can do when you’re using wool dryer balls is to splash a few drops of essential oil onto them. By splashing a few drops of essential oils onto the wool dryer balls you can make your laundry smell awesome without having to use super chemically dryer sheets to do it!

Let the essential oil soak on the dryer balls for 10-20 minutes before you use them.  The more the oils are absorbed into the dryer balls before use the more slowly they will be dispersed in the dryer, and slower is better!
