That scent is now wrapped up in a nice little bottle. Accompanied by a little stopper, just add the essential oil directly to your dryer balls and let them scent your entire load.
If you've purchased my scented dryer balls before, I add three drops to each ball initially just to give you an idea of how much to use. Most people like just two drops to each as the smell permeates quite well for a while. Just add drops as desired.
There are approximately 400 drops of liquid in the 1/2 bottles that I sell so if you were to buy a set of four dryer balls and use four drops of liquid on each ball that would be over 25 applications! On the flip side if you've got a set of ten with four drops each that's 10 applications - so it's going to depend on how often you scent your dryer balls and how many you've got that determines how long the bottle will last you. I've got some people who scent their balls once a month and then some who scent them every few months! If you decide to get the 1 ounce bottle, that's double of what I just mentioned!
