Colored candles may frost (white coating) which is a natural occurrence with natural wax. This will not affect how the candle burns.
The knot candle is designed for decorative purposes, but if you do decide to light them, please place on an even surface with a heatproof coaster and do not leave unattended. We advise to only burn your candle for 1 hour the first time you light it, and a maximum of 1 hours each time thereafter.
As the candles are hand poured, the finish may vary slightly from candle to candle.
