This amazing aroma lamp is made of polyresin, but has such a shiny finish that it looks like ceramic! The detailed painting on this skull celebrates the Day of the Dead. About 3.5 inches tall and 4 inches long. To use it, pour some scented oil in the glass tray. Then put a lit tealight candle inside the skull, through the opening in the back. The heat from the candle will warm the oil and release fragrance into the air.
