Corning Ware Grab-It Casserole, numbered P-150-B, with a diameter of 5-1/2", 7-1/2" including handle, and 2-1/4" high.
This handy dish holds a nice bowlful (550 milliliters!) of soup or cereal. It is in good condition with no cracks or chips, but it does have some utensil marks on the inside and light wear on the outside bottom.
