The Set of Three Ivory Blow Out Timer Pillars includes three, tall, battery-operated pillar candles with a unique and convenient blow-out on/off feature. Each one has an ivory, wax coating with a flame-like bulb on a black “wick”. They have on/off switches on the bottom side and a subtle sensor underneath the bulb that knows when it is being blown on to turn the light on and off. Each candle has a versatile look that goes well with any decorative style to leverage the convenience of the hands-free operation. They measure 5” high by 2.25” in diameter, 6” high by 2.25” in diameter, and 7” high by 2.25” in diameter. Each one requires two AA batteries, not included.
