Keep your food hot for longer with the Food Warmers for Parties by Chef Buddy. Simply place the plate in your microwave for a few minutes, so that the center of the marble stone becomes hot while the plastic handles remain cool to the touch. Place chafing dishes, pots, pans, plates, bowls, and more on the food warmers to keep your side dishes, desserts, and leftovers warm while you eat. This warming tray can be used indoors during Thanksgiving dinner or outdoors for backyard barbeques with no cords or batteries required. Please note, the marble insert may vary in color and pattern due to the natural quality of the stone.
