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, keep them away from flammable materials and out of reach of children and pets. After use, let the candles cool completely before handling. To maintain their quality, store them in a cool, dry place. Don't expose them to direct sunlight or extreme temperatures, as this can cause the wax to melt or deform.
