The Corningware French White 23 ounce lid makes preparing, serving, storing, and reheating food more convenient and much less wasteful than plastic wrap or aluminum foil. This versatile lid is safe for use in the freezer, refrigerator, and microwave, and it cleans up easily on the top rack of the dishwasher. Made of non-porous, BPA-free plastic, this lid will not absorb food flavors, odors, or stains. This lid is proudly made in the USA.
