Using these candles is easy. Just place them in a standard taper candlestick holder. Light the wick and enjoy 6 - 8 hours of warm glow. For safety, keep them away from flammable materials and out of reach of children and pets. When the candle burns down, trim the wick to about 1/4 inch for a clean burn next time. Store the candles in a cool, dry place to prevent melting or warping.
