Using these candles is a breeze. Just place them in a standard taper candlestick holder. Light the wick and enjoy the warm glow for 6 - 8 hours. When it comes to safety, always 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 appearance, store them in a cool, dry place to prevent melting or warping.
