How do I prevent my candle from tunneling?

It is recommended during the initial and subsequent burns of your candle to burn long enough to liquefy the entire top layer of wax, which can take a few hours. Allowing the candle to liquefy from edge-to-edge will keep the opening wide and prevent tunneling. If you feel there is another issue affecting the performance of your candle, please email Customer Service at customerservice@veedaa.com.
