The Sara Exclusive candles look deceptively real. They are made of real wax, and the light from the lamps flickers like real flames. The three candles are battery-operated and can be controlled with a separately available remote control, allowing you to easily manage multiple candles of the same or different colors and sizes. In addition to the on and off buttons, the candles feature a timer function that allows them to shine for 6 hours, then remain dark for 18 hours, and then shine again for 6 hours, and so on, until they are completely turned off. The candle can only be timed with the remote control. Each candle requires two AA batteries, which are placed in the aluminum base at the bottom. The battery-operated lights create a cozy atmosphere and are particularly suitable for households with pets and small children, as there is no fire hazard compared to real candles.
