This necklace comes with 5 felt pads (mixed colours - may not be the colours shown), ideally, you assign a colour to each fragrance you enjoy. These sell very well at shows. You will find similar styles (although not as nice in my opinion) selling for $40 on Etsy.
Aromatherapy jewellery is a modern and great way to benefit from essential oils no matter where you are.
Surgical grade stainless steel. The pendant is a 30mm locket with magnetic closures and a felt pad inside to put a few drops of oil on as needed.
