Burn with care candles will drip.
How to use double action candles:
The color wax represents what you want to manifest, the black wax represents what you wish to remove or banish.
To use these properly you must turn the candle upside down and burn it from the black side first. This is called "butting the candle".
To do this you must cut off the tip of the candle and make the top the bottom base.
Next carve a new top on the black part of the candle. Light the candle and you are done.
