Using these candles is easy. Just place them in a standard taper candlestick holder and light them up. They're great for adding a touch of elegance to your birthday, wedding, party, or any event. When lighting the candles, make sure they're in a stable position and away from flammable materials. Keep them out of reach of children and pets. To get the most out of the 8 - 9 hours burn time, trim the wick to about 1/4 inch before each use. After use, let the candles cool completely before handling. You can store them in a cool, dry place to keep them in good condition.
