Vintage Pyrex primary colors mixing bowl set featuring the classic four-piece graduated nest. This mid-century set includes the yellow (404), green (403), red (402), and blue (401) bowls, all crafted from durable white milk glass with fired-on color exteriors. These iconic kitchen staples showcase the early T.M. Reg. Pyrex U.S. Pat. Off. backstamps. While they show significant signs of their history through surface wear and finish dulling, they remain functional examples of 1940s-50s American kitchenware.
