Aromatherapy necklace. Aromatherapy is one of the hottest trends today – essential oils show positive effects on relaxation, mood, pain, anxiety and more. Just add a few drops of your favorite essential oil to the included cotton wick to absorb the oil, unscrew the top of the kit and add the wick inside. Machined holes easily ventilate the aroma. Each Aromatherapy necklace includes an adjustable 28 in. chain, five wicks, an empty 2 ml aromatherapy sample jar and a black gift pouch. Essential oils are not included. This one has been hand-turned from Turquoise Tru-Stone.
