Starlite Smile's Aromatherapy Necklace Essential Oil Diffuser Set comes with Mom and Son Necklace - a Stainless Steel Pendant that easily fits on to your choice of the 24" stainless steel chain or the 18" black silicone necklace (with invisible clasp), 12 washable, refill pads in beautiful colors and a Black Velvet Gift Bag. This is one of the greatest gifts for mom, new mom gifts, baby shower gifts for moms AND gift to yourself. It's not just a necklace but carries the benefits of essential oils that we as EO-loving moms enjoy so much but sometimes don't have the time to pamper ourselves with often throughout the day. It's so easy to just put a few drops on your necklace before leaving the house instead of trying to carry our bottles everywhere. I love this necklace! -- Mikayla, owner of Starlite Smile
