For use in Original and Candlelier Lanterns. 3 candles per package. UCO has spent countless hours developing our special candles. Citronella oil is added to the candle to help ward off bugs! Wax formula, wick size, and other features were specially engineered to make these the ideal candles for our lanterns. Other candles can 'melt down' prematurely due to improper wax formula and can leave significantly more soot on the heat shield compared with our candles. We recommend using only UCO candles in your lanterns.
