This is the Mirro 9x13 baking pan that I use all the time. I love it so much, that I just bought myself a second one, to replace the other 9x13 pan I have. I bought this pan at the local ACE Hardware for just $6.99 over a year ago and I have never regretted it. The sides are straight up and not angled out like most, so it makes a nicer looking cake. The lid is metal as well, so I can put it in the refrigerator and put stuff on top of it, which helps me to have more space in there. It's nice to not have to use aluminum foil and have a nice tight fitting lid. I always use this pan when I have to take something off to a dinner or party. I even take cookies in it just because it has a tight lid and it's easy.
