Using these candles is easy. Just place them in a standard taper candlestick holder. Light the wick and enjoy the warm glow for 8 - 9 hours. When lighting the candles, make sure they're away from flammable materials and out of reach of children and pets. After use, let the candles cool completely before handling. To keep them in good condition, store them in a cool, dry place away from direct sunlight. This will prevent the wax from melting or deforming.
