Using your scented shell candle is easy. Just place it on a flat and heat - resistant surface like a candle holder or a plate. Light the wick and enjoy the lovely scent filling your room. When using it on a cake, make sure the cake is away from anything flammable. To keep your candle in good condition, trim the wick to about 1/4 inch before each use. This will help the candle burn evenly and reduce smoking. Store the candle in a cool, dry place away from direct sunlight to prevent the wax from melting or the scent from fading. Also, never leave a burning candle unattended.
