ChefLand 3-Compartment Microwave Safe Food Container with Lid/Divided Plate/Bento Box/Lunch Tray with Cover, Black, 10-Pack
These 3 compartment food containers could be fitted into a cooler. And they are leak proof it matters very little that they are propped vertically inside. Upon retrieval, it is easy to ‘unlock’ the front lid. The portions are good sizes. One tray will hold 2 apples, 3 bananas, and a good handful of grapes.
