Backflow incense holders are decorative items designed to create a visually appealing smoke effect. They work with special backflow incense cones that release smoke downward instead of upward. This unique design allows the smoke to flow like a waterfall, creating a calming and enchanting atmosphere. These holders come in various shapes and styles, often featuring themes from nature, mythology, or fantasy. When the incense cone is lit, the smoke cascades down the holder, enhancing the overall aesthetic. Backflow incense holders are popular for meditation, relaxation, and enhancing the ambiance of a room.
