Lucid liquid candles never burn unevenly, never melt, never drip or ever need to be replaced. Simply twist the top with a quarter turn to remove it. Fill the candle's reservoir with Lucid liquid and place the top back on the candle. Wait a few minutes for the wick to be primed. Light your Lucid candle as you would any other candle. Lucid liquid is pure parafin, which means it burns clean. There will be no soot or smoke released from burning. If you want to add fragrance, simply purchase a Lucid fragrance stone. There are 12 scents available. Lucid candles are the perfect candles
