Wax melts are pieces of scented wax, often designed in beautiful shapes, colors, and sizes, that release a beautiful aroma into the room when heated on the top of an oil burner. Unlike candles, you do not directly light wax melts as they don't come with a wick.  They contain a high scent volume, meaning they Scent for many hours, and the aroma lingers. Wax melts are economical. They contain less wax than many candles, and scented cubes can be changed to a new fragrance regularly.
