Made from real wax, they have a patented faux flame that is so realistic you won’t believe your eyes. What’s so great about them, beyond their realistic look and feel, is that they are completely safe. No flame, no chance of fire! Plus, they operate on a timer. Turn them on once to the timer position, and they will “burn” for 5 hours, turn off, and then turn back on again at the same time on the following day.
