Zak Designs 21in x 13.5in Large Gallery Serving Tray - BPA-free, Eggshell White GL

It has high walls to prevent spills and unobtrusive handles that are still easy to hold. Measuring 21 inches by 13.5 inches by 1.75 inches, the modular design fits two half-size Gallery trays inside, or you can stack it with trays of the same size, since the bottom edge will keep them from sliding apart. The tray is made of durable melamine, BPA free and dishwasher safe. You can use it anywhere, indoors or out, although you should keep it out of the microwave.
