Color LED Square Glass Bottle Diffuser: Glass Bottle Diffuser Gift Kit (Empty Bottle) + 200ml / 6.76fl Oz Perfume Diffuser Replenishment Oil - (Clarity), High Quality, High Quality Filling. This aromatherapy is an amazing work of light and shadow art. Transparent glass bottles are elegantly carefully carved. When the built-in color LED light is turned on, light flows inside the glass bottle diffuser. The bottle becomes a glowing place, and the soft halo creates a wonderful high-end visual atmosphere. Whether used as a nightlight to embellish dim corners or desktop decorations, its unique vertical light and shadow effects are enough to become the visual focus of the space, perfectly integrating practicality and artistic significance.
