This beautifully shaped diffuser vase is made from ceramic. Each piece is carefully designed and hand crafted by skilled artisans. We treat our diffuser vase as an art piece. Each piece is hand-made so no two pieces will ever be the same. Using pure natural fragrances, our Ceramic Lined Dots Diffuser gives you the power of aromatherapy in your own home, office, or spa. The essential oil is drawn through beautiful, natural twigs and diffused into the air, lasting 8 to 12 weeks.
