This is a vintage Pyrex refrigerator dish in the Primary Yellow color. The set includes a rectangle dish and a ribbed lid. The dish is made of glass and has a rectangular shape. It is a casserole dish that can be used to store food in the refrigerator. The lid is designed to fit the dish perfectly and has a ribbed texture. Please examine pictures for best description.  There are a few flea bites on the lid but no major cracks or chips. Dish itself has the silver markings on the and some of the corners show wear. Still for it age overall good condition and very useable. Happy to answer any questions or to bundle. Thanks for looking.
