Turn your car into a mobile Zen den. Plug this leather-handled diffuser into your car's power outlet (that old-school cigarette lighter), tap a few drops of your favorite essential oil onto the retractable wand and slide it shut to begin diffusing. The LED light at the end glows to let you know it's on - and the inside of your car will start to smell divine. Includes a two-hour auto-off feature, and two spare pads. Essential oil sold separately.
