Car air freshener diffusers are currently available in two scents - Rhubarb & Rose and Black Cherry. They can be hung anywhere in your car, but also come with a free vent clip so you can attach them to the car air vent.
To use: unscrew the wooden lid and remove the plastic stopper. Replace the wooden lid and tip the bottle for 5-10 seconds until the liquid soaks into the lid. Remove the wooden lid again and replace the plastic stopper followed by the wooden lid. It is recommended to repeat this process once a week to keep the scent fresh. If any of the liquid spills, clean it up immediately. Keep away from children and pets. If hung, make sure the diffuser is not blocking your view in any way.
