Calm your daily commute with relaxing, refreshing aromatherapy! The lipstick-sized Car Diffuser plugs directly into your vehicle’s DC outlet (cigarette lighter) to gently disperse your favorite soothing scents. Simply place 2-5 drops of essential oil on the included scent pad, insert the scent pad into the aroma tray, and plug in the device. A sliding switch with LED indicator light lets you control the intensity of the fragrance. Includes 1 long-lasting scent pad. Essential Oils and Extra Scent Pads available atSharperImage.com.
