This is the complete set of 4 covered Primary Colors fridge storage dishes by Pyrex, introduced in 1947. The largest yellow dish is 1-1/2 quarts, the middle size blue is 1-1/2 pint oblong, and the two smaller dishes are both 1-1/2 cups. The dishes all have the early style lids with narrow ribs on the long sides only (later sets came with fully ribbed lids).

The dishes are in excellent condition. They still have their glossy finish and bright, bold colors. When held to the light, the blue and red dishes have a few scattered pinpoint specks of color loss, probably just from storage - they've never seen the inside of a dishwasher. There are no utensil marks or stains inside any of them, and the lids are pristine with no chips or flakes. One red dish has a long shallow scratch on the side (photo 5). The yellow dish has a faint silver rub mark at one bottom corner (photo 7, upper left corner), and an old taped name label on the bottom. I left it there because removal will leave old sticky residue, and I'm out of Goo Gone.
