Ok, I'm being honest here, I have NO clue what this is. My kid moved away to college and I believe it was gifted to him on his birthday, from what I can Google, its some kind of aromatherapy station. You insert a candle in the back and the heat rises to warm the aromatherapy up top, or its some kind of candle/wax melter. Its missing the top piece, but has been used fine without it.
