These reversible cozies are great for hot or cold items. Put the bowl inside cozy to microwave your food. Remove by lifting by tips of the cozy. The dinner plate size fits most standard 10-inch dinner plates. The soup bowl size is 9 inches diagonally, 7 inches on the side. Because these are handmade, they will vary slightly. These cozies will fit up to 6-8 inch bowls comfortably. The pint-sized cozies are perfect for your morning cup of oatmeal or Ramen chicken noodle cups, or a pint of ice cream to keep your hands from getting cold. Made with cotton material and Wrap n Zap batting. This batting is specially made to be safely used in the microwave. Machine washable in cold water, reshape and air drying would be best.
