The Better Homes & Gardens Wicking Ceramic Floral Oil Diffuser features a handmade ceramic flower on top of a decorative white ceramic basin. This unique ceramic flower diffuser fragrances the air while enhancing your home or work environment with soothing aromatherapy. The Better Homes and Gardens Wicking Ceramic Flower Diffuser works by dispersing 100% pure essential oil or Universal Fragrance Oil directly into the air without the use of water by absorbing pure essential oil through a wick in the reservoir up through the decorative ceramic flower. Combine your favorite essential oils to create custom blends. The Better Homes & Gardens Wicking Ceramic Diffuser is an easy way to personalize your space. Please note that the oils may change the color of the flower on the diffuser. (Better Homes & Gardens essential oils are sold separately)
