Ready to bring some of your favorite Mad House scents into your car? Our new car diffusers hold 6 ml of fragrance. They can be hung from your rearview mirror, RV Bathroom, Closets, or other small spaces! The diffuser bottle is shipped with a plastic plug under the wooden lid to seal it. When the plastic stopper is removed and the wood lid is replaced, you can gently tip the bottle to allow some of the fragrance to soak into the wood cap. Then just turn the bottle upright and hang! Directions for use will be included with your purchase. Currently offered in a few of our best-selling scents as well as NEW ones! *Warning: Over-saturation can cause leaking, which may damage surfaces. Avoid contact with skin, eyes, textiles and furnishings.
