I found these nice stackable paper trays at Dollar Tree and bought some to keep my copies organized for the week.
I've included an editable page in case you wanted to label your trays with something else.
They would work great to organize Literacy Centers or Math Centers.
You can read more about them here
Just wanted to share! I hope you find these helpful.

Thanks for looking and have a wonderful day!!!
