Trimming your candles properly is so important, not only does it help prolong the life of your candle but it also ensures the candle will burn safely. These wick trimmers are super high quality, very sharp so will give you a nice clean cut on your wicks. The angles design helps reach into deeper vessels and the raised edges on the trimmer helps keep the spent wick on top of the trimmer so it doesn't fall back into the candle.
