Pyrex Replacement Corning Ware Lid 9 1/4" x 7" Clear Glass F-12-C in Excellent Condition! Oval in shape. No damage, chips, or cracks noted. I just took in two new ones to bring my total back to 4. One of the new ones has a couple of minor chips and they are actually hard to see. They remain cosmetic and will not affect the ability of the lid to function. There may be slightly difference in styles (decorative ribbing on top), but they are all F12C. Condition is "Used". Shipped with USPS Priority Mail.
