I make these tea light candles with a blend of my beeswax and purchased beeswax. I use both metal and plastic cups when I pour the candles, so that my product can be used in a variety of situations. Tea lights in plastic cups are best in open containers, and the tea lights in metal cups are best in closed containers as the cup will not melt if the temperature in the container get too high. Each box contains 12 candles. The assorted tea light box contains 6 plastic and 6 metal tealights.
