Using these candles is easy. Just place them in a standard taper candlestick holder. Light the wick carefully, and enjoy the warm glow for 8 - 9 hours. When lighting, make sure the candles are on a stable surface away from flammable materials. Keep them out of reach of children and pets. After use, let the candles cool completely before moving them. To keep them in good condition, store them in a cool, dry place away from direct sunlight.
