These unused, mostly still in originally packaging, plastic knives, forks, spoons, plates, "glasses" and "champagne flutes" were *unused* remainders from a large family celebration many years ago.
They have been in a sealed box since then.
I haven't counted them but estimate a few dozen of most, with just a couple of plates, as shown in the photo below..
If some one is having a party, maybe they can use them. If not they will end up in the rubbish anyway, so how does one dispose of non-recyclable plastic these days?
