Finding a rectangular pyrex pan lid is a treat! I used to put shower caps over them and hated that they always got smeared with whatever was in there and throw away eventually. These are easy to keep clean, you can bake with them, keep things in the fridge. They even fit my metric sizes from Brazil ... they just make your life neater and simpler. :) Gotta love it!
