Set of stackable red triangular pizza cases (Tupperware) I mainly used these when buying and taking out pizza from Costco. I used them a few times and am now selling them because I no longer need them. You can store them in the freezer, refrigerator, and even heat food in them. They can also be used as lunch boxes for picnics. - Color: Red - Shape: Triangle - Material: Plastic - Set includes: Multiple sandwich cases - Lid features: Snap-on lids - Design: Stackable Thank you for looking.
