We have an old set of Tupperware dinnerware.
They are so old they are vintage now. We use the plates and bowls. I'm sure the mugs are somewhere around the house but we don't use them.
These things are indestructible. We use them when we don't use paper or plastic. The nice thing about them is they are heavy and don't have a completely plastic feel. I don't even think they show knife marks. Not sure if Tupperware is still into dinnerware. My wife
used to be a dealer so we have a lot of it.
