Package of 3 clear plastic floating discs and 50 mini wicks. Just insert a mini wick into the disc, fill a bowl with water & float 1/2" of vegetable oil on top, and float disc on the oil. Some of the oil will enter the grooves on the disc and will be used as fuel for the wick to burn. Disc becomes almost invisible and makes beautiful centerpieces! Each wick burns for approximately 6 hours.
