RRD 40 - 3.5" height candle wicks are used in making 2.25" to 2.75" diameter container candles. They are pre-waxed and have a wick tab attached. RRD Wicks burn hotter than LX series wicks making them ideal for candles made using soy, beeswax, palm or other natural waxes. 

Before making multiple candles, always do a test burn on each combination of candle size, wax, dye, fragrance, and wick. For optimal burning allow candle to set for 48 hours before lighting.
