Exactly what I needed
Size: 100 Pack
These are great for making cleanup from cooking easier. Like most disposable pans, these are a little on the flimsy side when loaded with food, but I either put them on a cookie sheet or inside another baking pan for loading into and out of the oven, and they work great that way.

Horrible quality. Manufacturer has created absolute junk.
Size: 100 Pack
I have bought these pans many times and I’ve been very happy with them. However, the most recent batch I got of 100 was shockingly inferior to what I received before they are of such poor quality that they bend like a piece of aluminum foil. they are dangerous to cook with if you pick them up. They just bend. Usually, they are packed in a carton which then is inside the Amazon box. This time, they were just in the Amazon carton and then arrived crumpled and crushed. Wherever they bought them from is a disgrace. I will never buy them again. They are a disaster and dangerous to use in your oven.

Good stuff
Size: 100 Pack
Excellent materials. As advertised-no surprises with finding stamped foil that doesn’t hold its contents. My wife uses these to bring food to my work and she is perceived as a professional chef.

Would probably buy again.
