Choosing our tarts is a great way to sample our scents. Our melts are packaged in an easy to use plastic clamshell. Simply, break off 1 or 2 melts and place them in your tart warmer. Keep the lid closed and store the remaining melts in the clamshell for later use. Make sure to keep them away from the direct sunlight. Each clamshell holds 6 melts that are each 1" square. Total weight of melts is approximately 3.5 oz.
