Introducing our aromatherapy diffuser necklaces! These necklaces allow you to take your favourite essential oils or one of our special blends with you wherever you go, while also reaping the positive health benefits they provide. The lockets come in two sizes, 25mm and 30mm in diameter and 5mm in thickness, and are made of stainless steel to prevent the oils from tarnishing or breaking down the metal over time. Each locket contains a small pad that can hold a few drops of oil. The oil slowly diffuses through the ventilation holes on the front and can linger for several days. If the scent fades away, you can always add more oil to the pad to keep it going
