A properly trimmed wick is important to maintaining the lifespan of your candle. The proper wick height allows you to get a clean and even burn to the edge of your candle, without tunneling or risk of excess smoke. Set the wick trimmer above the top of a cooled candle and snip the end. The wick trimmer will catch any trimming fallout for easy disposal. We strongly advise trimming your candle wick to 1/4" before each use.
