Pottery stone diffuser Their Pottery Stone Diffuser ceramics' to emulate natural stones. Drip a few drops of the Diffuser Oil on the stone. As the oil seeps in, the fragrance starts to slowly disperse. Just like when you bring a stone home from the beach, the Pottery Stone Diffuser gives you the feeling of inviting nature into your home. The stones are available in three shapes. Stone 1 has an adorable round shape. Stone 2 is slightly angular and is most stone-like. Stone 3 has a more elongated shape. All shapes are designed to complement each other. You can collect all three to display them together. The stones are the results of our times-taking collaboration with Shigaraki potters. Each stone offers its unique quality, so the one you select will be one- of-a-kind. We only produce limited number of stones for each shape, and each stone comes in a box that is numbered. The stones are designed to absorb the fragrance of the oil. We recommend using one fragrance per stone and not using multiple fragrances on one stone.
