I use 1cm felt balls in the car air freshener buddies. All you need is to add a few drops of whatever oil you like to the ball. Add more as needed once the smell dies out. If you need replacement balls, you can get packs on Amazon. You can use a different color for different scents!

FELT BALLS

I recommend using essential oils on my car air freshener buddies. Linked are some oil companies I can recommend to newbies. You can also search for essential oils on Amazon for a variety of brands. My personal favorites are citrus scents.
