Using these candles is a breeze. Just place them in a standard taper candlestick holder. When lighting, use a long - reach lighter or match to avoid burning your fingers. Keep them away from flammable materials and out of reach of children and pets. For a longer burn time, trim the wick to about 1/4 inch before each use. After use, let the candles cool completely before handling. Store them in a cool, dry place to prevent melting or warping.
