Easily create a candle that will hold a tea light with this nifty device. Simply put the polyurethane plug into the bottom of your mold with the embedded screw poking out of the wick hole. Screw the nut on the outside of the mold and attach some mold sealer to secure everything. Pour the wax into the mold, let it cool thoroughly, then undo the nut, slide out the finished candle, and remove the tea light plug. Insert a standard tea light into your candle and you're done. The Tea Light Insert is reusable.
