These are our NEW car diffusers. Beyond cute and will fill up the whole car with a scent of your choice. Easy to use and great as gifts. We have our Car Fresheners in 31+ scents. Please see our Scent Description page in the images for any of the scents that aren't obvious by their titles! Instructions: * Unscrew cap and remove the plastic stopper when you're ready to use it. * Hang your car diffuser from your rearview mirror or in your office. * Flip the bottle upside down to allow the fragrance oil to wet the bamboo top. Return it right side up. Anytime the scent is getting dim/low, feel free to tip the bottle back over and repeat.
