Using these candles is easy. Just place them on a heat-safe plate or a candle holder. They are great for adding a warm atmosphere to your home, weddings, churches, restaurants, or any event. When using, make sure to keep them away from combustible materials and out of the reach of pets and children. Never leave a lighted candle unattended. After use, simply blow out the flame. There's no special maintenance needed, but storing them in a cool, dry place will help keep them in good condition.
