Wick Trimmers are a candle game changer! Not only do they make it easier to reach down in side your pillar and jar candles, but the circular plate prevents any ash from falling into your candle of any shape or size. For the longest and most efficient burn, you want to trim your candle wick to 1/4in - before your burn and during your burn about every hour. This keeps your candle clean and beautiful and burning down evenly and wonderful!
