The iconic Stone Diffuser scents your home naturally using 100% pure essential oils and doubles as a piece of decor. I'm including a box of brand new essential oils, too (energizing Grapefruit, calming Lavender, refreshing Spruce, and invigorating Eucalyptus). Both are brand new in box, never used!
