These aromatherapy diffuser necklaces will allow your customers to wear your favourite essential oil or one of our special blends wherever they go while also experiencing the positive health benefits they provide.  Each locket contains a tiny piece of pad which holds a few drops of oil that slowly diffuses through the ventilation holes on the front. The scent of your oil can last for several days, but you can always top up more oil to the pad after the oil has completely diffused.Lockets are available in two sizes 25 mm and 30 mm in diameter and 5 mm in thickness and are made of stainless steel to ensure the oils do not tarnish or breakdown the metal over time. Each necklace comes with 10 assorted colour pads.The back of the locket is solid and we offer choice of 12 beautiful laser cut designs to choose from. The lockets can be opened via a tiny slit on the right which is held together with a strong magnetic closure.
