These candles are easy to use. 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. Never leave them burning when you're not around, and make sure kids and pets can't reach them. There's no need for special maintenance, but store them in a cool, dry place when not in use. These candles are perfect for adding a touch of elegance to your home, weddings, churches, restaurants, or any event.
