Clamshell wax cubes come in the standard 6pc size filled with 2.75 Oz of 100% soy wax. Place 2 to 3 cubes into wax warmer and then turn on warmer to melt cubes. When wax is melted and you're satisfied with your now fragrance filled room, simply turn off warmer until ready to use again. To clean, melt left over wax and place a couple of cotton balls into warmer to soak up wax. Wipe away left over wax and reuse warmer with desired wax melts.
