1970's Metal Lunchboxes With a Glass-Lined Thermos
For children. Inside a metal lunch box. Didn't matter if it was Barbie, Hong Kong Fooey, or Hot Wheels; the Thermos bottle had a glass lining. The lining would last approximately two days, if it didn't in fact break on the way to school. I remember actually pursing my lips and actually drinking my milk through the glass. It took the lunchbox people around eight years or so figure out that it was a bad idea. See also 70's, Children, Schools.
