100% Soy Melts. Break a cube off and put in your tart melter. They should last up to 5 hours. Mix different cube scents to make your own unique aroma. These have more scent added than the candles, to give a great throw of scent. These are small cubes 1" X 1" X 1" http://www.MyTroddenPath.com/Store/aGo.asp?aff=559
