Vintage Tupperware Square Cake / Cheese Container

Vintage Tupperware Square Cake / Cheese Lidded Storage Container. Beige Cake Plate #788 with opaque Lid #789 I was not able to find this item so I assume it is Rare. One listing said it was for cheese but it seems more like a cake container to me. It is in good used condition with only minor marks from normal usage. While the lid does lay slightly warped on the counter, it still has a nice fit onto the plate bottom.
