This has been a great addition to my workshop. The tray is removable so I can take it to my workbench and then back to my project. The tray isn't virtually square as indicated in the image (I reported this to vevor) but 325mm x 265mm x 40mm. Unfortunately, Vevor doesn't sell extra or replacement trays, but they are the same as Gastronorm Trays (1/2 size) used in the kitchen industry, although 40mm versions are not that common, and it's not possible to fit anything deeper. I purchased 3 extra trays with lids to keep my projects organized.
