Aroma Ornament A ceramic aroma diffuser for room fragrances. Put a few drops of essential oil directly onto the diffuser and let it soak in. You can use any essential or perfumed oils, but some of such aroma oils might cause colour migration or spots on the product, so you are encouraged to test it on an inconspicuous area, such as the back side, before use. This product is fragile, so please handle with care. Because they are entirely handmade, designs and forms may slightly differ.
