How do I make sure the candles don't drip?

After making sure the candles are securely placed in their holders, melt the bottom of each (Taper)candle to help it stick firmly and stay upright. Avoid placing them near drafts such as open windows, fans, AC units, or in windy outdoor conditions.

Keep in mind that even with these precautions, some dripping may still occur. When used as directed, D'light Online candles are designed to burn smoothly and evenly.
