Heavy duty plastic. Very sturdy material. I love that they are lined.
Was supposed to be gray lining. They're a nice size so i’m keeping them, but they definitely slip around.
When i saw it it was very skeptical but believe me, it works. This saves so much time for me. Too many unnecessary rubber pieces but other than that, works well.
The tray is sooo easy to clean. The red silicone feet are easy to remove for washing. I have health issues so depending how i am feeling is the results of me fixing supper or if it's help yourself in the kitchen.
While the functionality is fine as far as it goes, the black coating starting peeling pretty quickly, so the food needs to stay in its packaging or placed in a plastic bag. Absolutely pointless.
Mostly unreliable reviews. Do more research before proceeding
