The Pyrex 7212-PC blue lid fits the 6-cup glass dish (sold separately). This 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. PLEASE CHECK THE BOTTOM OF YOUR DISH FOR THE NUMBER “7212” TO ENSURE A PROPER FIT. THIS LID IS NOT COMPATIBLE WITH ANCHOR HOCKING PRODUCTS.
