Wax melts are an alternative to candles. Take one or two melts, and place them in your warmer - some are lit above a tealight, and others are electric. When finished, remove the heat source, or turn the electric warmer off, for the wax to solidify. Repeat until the you can no longer smell the wax.
Each pack contains 6 melts, and typically last 6-8 hours each.
