This is a set of 3 chimney bobbins with moving flame remote-operated 4-inch tapers. The tapers are coated in tranquility, tapioca, and our special silicone recipe. This silicone is designed to resist cracking and melting. Each candle requires one AA battery (not included). Please note that a remote control is necessary for operation and is sold separately (item #04-02549). The remote allows you to turn the candles on and off or set them to a 6/8 hour timer. One remote can control multiple candles. Dimensions: 12" x 2", 12''x2'',11x3'',10''x2''
