Corning Ware 2-3/4 cup/700 ml Petite Pan casseroles from Corning Glass. According to the Corningware411 site, this "All White" style of Corning Ware was available from 1962 to 2000. This is the original Corning Ware Pyroceram glass and ceramic material that can go from freezer to oven to table top, not like the current stoneware that is not as versatile.
These cunnin' little casseroles are the P-43-B and are in very good condition with light wear. A unique feature of these Petite Pans is that they can act as covers as well. The small flange along the inside edge of each handle locks the upside-down petite pan in place and makes a perfect lid with a little vent. Because of this, I recommend that you buy TWO of these! (And remember, I combine shipping!).
