We had a few pieces when I was younger, that my mom got at parties hosted by her friends or our neighbors. We had the cake carrier, pie saver, a measuring cup/pitcher, half gallon pitcher, and a couple small bowls.
Interestingly enough, a couple of the neighbors never had Tupperware or other plastic storage, but glass (Pyrex) storage containers, metal cake carriers, and glass or ceramic bowls.
I might have a piece or two of it left, but it tended to become brittle and crack over time. Both the pitchers cracked and leaked after a while. What I do have is a couple Cambro storage containers, which are NSF listed, and made of hard plastic - polycarbonate I think. Those are about 35 years old, and still like new.
