I have a variety of serving trays - maybe 4-5 in different sizes and shapes - white and black - the sort you get from Wegman's catering, I think. Pretty sure they can't be recycled and I can't stand throwing them away. They are a little fragile, but with care you could re-use them many times.

I can send exact sizes if needed.
You pick up near Brooktondale.
If you could use this sort of thing in the future, let me know. I am likely to acquire more over time.
