An 18” pizza could easily fit into the storage container, not really. The separators are just too small to be effective at all for the average sized pizza slice.

Aluminum is one of the better metals to use as a pizza pan. It's not only light weight, it conducts the oven heat very well. It came flawless and shiny. Fits in a standard oven too.

They only bevel up 3/8 and a lot less of the pan is beveled. Looks like they played frisbee with it prior to shipping.
