Diffuse your essential oils or blends as you wear a cute, locket necklace. Remove the locket from the chain and open it. Place a drop of essential oil or blend on the bead and rub over the clay bead, then allow it to absorb and place it in the locket. Close the locket and put it back on the chain. The chain is 27" and it comes with 7 assorted colored clay beads.
