The lockets on these bracelets contain beeswax. Add a couple of drops of essential oils on the beeswax, they are absorbed, and then naturally diffuse when the bracelet is worn.
To replace the scent, simply rub the beeswax with your finger and the warmth will rub the current scent off. You can then put a new scent on the same beeswax!
Each locket is made with hypoallergenic stainless steel.
