The oil burner is designed to work with either wax melts or essential oils. A tealight candle is inserted in the bottom and lit. If using wax melts, 1 or 2 cubes are put on top, if using essential oils start with a bit of warm water and add as many drops of oil as you prefer. The heat from the candle will warm the wax melt or the oil and softly enhance the room's aroma. This is a fair trade item from Tyendinaga Mohawk Territory.
