Using these candles is easy. Just place them in a standard taper candlestick holder. Light the wick and enjoy the warm glow for 6 - 8 hours. When lighting, make sure the area around the candle is clear of flammable materials. Never leave a burning candle unattended. After use, let the candle cool completely before handling. To keep them in good condition, store them in a cool, dry place away from direct sunlight.
