Our Cement Look Pillar is a safe and classically-beautiful candle that operates on two AA batteries (not included) with a timer option! It stays lit or six hours and off for 18, with a flickering, flame-like bulb that has been dipped in silicon for a realistic affect. It measures 3½” high by 2¼” in diameter, and looks great on a tabletop or shelf alone or inside a floral ring!
