This cool candle holder makes your candles last twice as long! Underneath the candle there is a chamber that contains a second wick. As your candle burns the wax collects inside the chamber and a second candle is formed. After the original candle has burnt out then you can burn the new candle. The new candle is of course just the old candle but with a new wick! You can open the chamber which serves as a mold to remove your new candle. If you wish you put it in the same holder and recycle it over and over again until there is not enough wax left to do so.
