Hand-carved design featuring a water-proof Liquid Quartz sealer on the outside. This design can be used as a bud vase or essential oil diffuser. To diffuse, simply add pre-mixed scented oil and place bamboo diffuser reeds inside. For homemade scented oil, add a few drops of quality essential oil to a mild carrier oil like almond or jojoba. Made with a narrow opening to inhibit evaporation.
