The WMF baking dish not only meets my expectations of a decent shipping container, but is also qualitatively sound. The ordered me size than enough for a lasagna for 6 persons including lookup.
It fit three standard lasagna plates next to each other and just over 7 superimposed layers.
Material is so valuable and stable, as explained in the product description.
From me there is an absolute buy recommendation for the WMF baking dish.
