Vintage Pyrex white Opal 501 Fridgie w lid

Years Manufactured: 1950s
501 (1.5 cup) white Opal Fridgie
Not too much to say about these Opal White Refrigerator Dishes, except that they are a little more uncommon than your average ordinary refrigerator boxes in yellow red or blue.

Introduced in the 50s, these have the usual clear lids along with solid white opal color with no design on them at all.
No chips or cracks
