This cute little crock pot is NOT FOR FOOD. This vintage darling is a potpourri warmer. Add a little potpourri, essential oil, or herbs with some water and turn on for a nice fresh aroma in your home. May work with wax melts? Try at your own risk. Minor wear in the form of browning on the inside from the warmth. Item has been tried and tested- works like a charm! All proceeds go to supporting my kitten rescue and foster work.
