They’re the perfect addition to any car or tiny space that needs a scent refresh! To use them, untwist the wooden lid, remove the plastic plug/stopper, twist the wooden lid back on. When the lid is on, tip it upside down. This will cause the oil to soak into the wooden lid and diffuse the scent into the air! Then hang it in place and enjoy! Occasionally, flip it upside down to re-soak the wood, or if you hit a pothole or bump and it jostles around a bit, you’ll notice the scent reactivates in that moment. Hitting curbs has never smelled so good ;)
