I like the scent even though vanilla isn't usually my favorite. You breath the cubes and use one or two at a time in a wax warmer or tart burner like the ones from Yankee Candle, Scentsy or any other brand. The Scentsy burners use electricity (a small lightbulb) & Yankee and most other brands are lit from below with a tealight candle. Hope that helps!
