Pop 1-2 teaspoons in your burner, the oil will evaporate and create a strong & instant fragrance within your home.
One teaspoon lasts up to 6 hours - the crystals will not melt or evaporate, just the oil. Once the scent has run down simply dispose of the crystals and they will leave a mess-free burner.
Can also be used to fragrance wardrobes, handbags, gym bags, cars etc by adding crystals to an organza bag. (1 supplied with each pot).
