I love Anchor Hocking. A few years back, I received an Anchor Hocking Oven Basics casserole set. Mine was round but other than that, this is the same thing. I love this! I love making things for a pot luck or party and carrying it with me. This comes with a thermal jacket to carry and keep it hot or cold.
I have had many ask about it and as far as I know, they have all purchased one too. Keeping things hot when needed or cold is an easy thing to do with it. It has a rubber kind of top that I can put on the dish even if it is hot and it continues to work without losing shape and fits perfect every time you use it.
Have something cold? This works to keep things refrigerated. No more worries. I really recommend The Anchor Hocking Oven Basics. It just won't let you down.
