This is a vintage blue MCM Pyrex lidded refrigerator storage dish.The dish is marked 502 B/ A 35. The dish has minimal scuffs and wear which can be seen more visibly when held up to the light.There are no chips or cracks and it is nice and clean.The lid is clear glass and ribbed.It is stamped 502 C.The lid is clean with minimal wear on its edges.No cracks or chips BUT there is an area on one corner of the lid(see photo) that has a rough area.I am not sure if it is a manufacturing error or possible a wear scuff/ chip but it is not sharp or rough to the touch just can be seen slightly and you can feel it when you run your finger over it.I try to show and describe items thoroughly so the buyer knows the condition and wear.It is 6.5" × 4".Pre owned and sold as is as described and photographed.
