• Trimming your wick keeps the flame in control and ensures your candle isn't getting too hot from too big of a flame • trimming your wick before each burn removes the "mushroom" that often is created on top of wicks after their burned. this mushroom is a carbon buildup from the wick and is completely normal - but needs to be removed each time to ensure the wick is burning properly • reduces excessive soot build up by keeping the wick trimmed (if your wick is sparking or popping it's too tall + needs to be trimmed!) • by keeping your wick trimmed increased the longevity of your candle by keeping the wick at just the right temperature (not too hot!) purchase a wick trimmer here
