The diffuser is specifically designed to work with Estéban’s refresher oils. It also works with essential oils used in aromatherapy. The flame design represents ethnic motifs, on this black ceramic fragrance diffuser. The scents are intoxicating. Drift under the spell of the charms of Africa. Tips Just a few drops of one of our refresher oils with a little bit of water in a fragrance diffuser will create a perfumed and welcoming atmosphere. The intensity of the fragrance varies from one refresher oil to another. We suggest that you experiment a little in order to discover the dosage you prefer. Please note: refresher oil is not part of this package. It must be ordered separately.
