Scent Profile: Coconut, Honeydew Melon, Lime, Agave, Green Floral, Green Leaves Powder, Violet Our car diffusers are made with sustainability in mind. We use EcoBase™ Diffuser Solution that is: Non-toxic, Di Propylene Glycol (DPG) free, Volatile organic compounds (VOCs) compliant in all 50 states. Made with renewable resources and 100% biodegradable. Packaged in glass with wood top. Directions: Unscrew the wooden top of your diffuser. Remove the inner cork stopper. (use scissors to wiggle the stopper up and out) Screw the wooden top back on. Hold upside down for 3-5 seconds (over a paper towel, incase it drips), allowing the wooden cap to saturate with fragrance. You can place the stopper back on if you want a light diffuser Tie the rope above the wooden ball and hang in your car or room. Safely first: do not hang on the turn signal switch, gear shaft, or windshield wipers switch When the wooden top is dry and you can no longer smell you can repeat the steps.
