Various Scents are available from the drop down menu.
The air freshener itself is an elegant glass bottle with a silver plastic lid filled with cork. You simply take out the safety cap, place the lid back on tight & turn upside down for no longer than 3 seconds. (I'd advise doing it outside as if you hold it for too long upside down the fragrance can seep through the cork and leak!). The fragrance will gradually allow the scent to fill your car and they can last upto approx a month, sometimes longer!
