Vent N Serve set of 2 vintage Tupperware containers with lids and vents Preloved

Vent N Serve set of 2 vintage Tupperware microwave containers with lids and vents Preloved in great condition. Minor scratches from age and wear. The one container does have 2 areas with what appear to be cracks but they cannot be felt from inside or outside of either. So still very useable and have many years left I’m sure. #18 .
