Commercial Quality Baking Sheet Pan Set, Natural Aluminum Cookie Sheet, Umite Chef Warp Resistant Nonstick Baker's Quarter Sheet Pan, Thick Cookie Tray Pans for Baking, Roasting(2 Pack,13i *9.5inch)

Sturdy durable and useful for all of my baking needs. They haven’t warped, rusted and have cleaned up easily. Would purchase this again.

I should have read the description better because these are small sheets!

Quality of item is beyond expectations Cooking quality and heat transfer is excellent Highly recommend this item

Love these, cleans so easily and completely, no browning from constant use so they don't appear ugly like other pans used in the oven. I bought more! Great gifts for family.

I wish I had read ALL the information before using these pans. I put virtually everything in my dishwasher and didn't even think twice about it when I put my tray in the dishwasher after the FIRST use. I'm so disappointed with how horrible it looks now. Lesson learned! Although I can't really fault the product for it because the directions are posted, I'm still knocking off one star for their lack of versatility. When I read the product information, I also noted that vinegar, tomato, and other acidic foods would harm these sheets.
