These red, blue & gold anodized aluminum bases bowls are 2” high x 5-3/4” wide rim to rim. They were usually used as cereal or snack bowls in the 1960s.
As can be typical with Mid-Century Modern aluminum items, there are some light scratches present and the red bowl has very minor rust, but don’t let those things dissuade you from owning and enjoying these fun and very cool bowls!
