Excellent Pyrex Primary Colors Nested Mixing Bowl Set Just like Mom's or Grandmother's circa 1940 1950, a classic American Icon and design which still functions in the kitchen and evokes so many memories. My Mom still has hers and uses it to great effect in her kitchen. Here's great set in excellent condition consisting of big yellow bowl (perfect for popcorn, or salads as so many people say), green, red is bright with none of the usual typical fading and blue is in excellent condition, one of the nicest I have had, no scratches, paint bright, no chips, cracks. Interiors clean and bright white. The only flaw I can find are a few tiny scratches on the yellow bowl. (See last pic). They are the 400 series Smallest to largest: 401 - 1.5 pint 402 - 1.5 quart 403 - 2.5 quart 404 - 4 quart All in all a splendid vintage set! Great for your vintage or retro kitchen. A perfect gift for Mother’s Day.
