I have all the original Tupperware I got when I was first married the first time around 1965. Avocado Green and Harvest Gold. They work fine. I still use the canisters for flour, sugar, brown sugar. I have found the yellow strainers to add to my original one, and I have my original lettuce keeper and lucked upon a spare about 4 years ago in an estate sale, with the insert. I still have all my original corning ware from back then and have found a few pieces at the Goodwill and they still look good and serve their purpose. I am almost 81 and they will not be part of any "Swedish Death Cleaning", haha.
