Mid-Century Massimo Vignelli for Heller Lidded Bowls - A Pair

I don't buy a lot of plastic, but these classic Heller lidded bowls are so good, and cheerful, and useful, I couldn't resist, and really they transcend. Designed by Massimo Vignelli in the mid-60s, they will likely last forever, and are the perfect thing for storing, and then eating, leftovers, but also great just kept on the counter filled with with little treats. 

5" d x 3 1/8" t with lid; 2 3/8" tall without lid. Very good condition, with light wear. There is one tiny chip/flea bite on the bottom edge of the yellow bowl. SOLD AS A PAIR. My photos of these are not good, and I should have scrubbed them more thoroughly before taking them, but they are really bright and lovely.
