Inherited a small collection of antique and vintage items I don’t need. This is the A-10-B 9.75" x 9.75" x 2" La Romarin Corning Ware / PYREX casserole dish. Made in the U.S.A. For range and microwave use. Includes original clear glass lid. Dish is in great condition - very few interior scratches despite years of use. Zero wear to pattern on either side of dish!
