This is a good quailty aromatherapy necklace. It has a nice size locket that securely closes. There are 7 different colored felt discs to use so you can wear different colors and use different oils. I like that it's stainless steel so I don't have to worry about it tarnishing or turning my neck green from wear. The chain is a good length too. The felt discs are thick so they hold the essential oils well without leaking.
