Using these candles is easy. Just light the lead - free cotton wick, and enjoy the warm glow and gentle scent. When lighting, make sure the candle is on a flat and heat - resistant surface. Keep it away from flammable objects and out of reach of children and pets. To maintain the candles, trim the wick to about 1/4 inch before each use. This helps the candle burn evenly and reduces smoke. If the candle is not burning well, check if the wick is too long. Don't leave the candle burning unattended for long periods. After use, let the candle cool completely before moving it.
