Car Scenter, (#7086 - item) is the perfect car air freshener from our range of innovative aromatherapy diffusers. Surround yourself with mood-enhancing natural fragrances whenever you're on the road. Simply apply a few drops (2 to 5) of essential oil on the reusable pads and insert into the aromatherapy diffuser. Plug the diffuser into the car lighter socket and within minutes you'll experience the benefits of your chosen pure essential oil. Unplug the diffuser if the light remains lit after turning off the engine to avoid draining the car battery. A refill pad may be used until it hardens and/or discolours. Comes with five refill pads.
