Wax melts are highly fragranced cubes of wax without wicks in them. The cubes are placed into a melt warmer where they gradually warm up and melt, releasing the fragrance. Our melts include soy wax melts in a clamshell tray. Place 1-2 cubes at a time into a melt warmer and change when the scent fades. Usually last 4 or 5 burns.
