Using these candles is easy. Just place them on a heat-safe plate or a candle holder. Light the wick, and enjoy the warm glow for up to 13 hours. Remember, always keep them away from things that can catch fire, like curtains or papers. Never leave a burning candle alone, and make sure it's out of reach of kids and pets. When the candle is done burning, let it cool completely before moving it. There's no special maintenance needed, just keep them in a cool, dry place when not in use.
