In fact 500 sheets per package. How could they pack those 500 sheets into a package that I could easily hold? Rather than pack them side-by-side they put them on top of each other. You see a sheet of paper is very thin but 8.5 x 11 inches wide. So they arrived stacked on top of each other in a package only about 2 inches high. Unfortunately they didn't have the information on them that I would have liked. No matter; I have a thing called a "printer". I take a chunk of the package (100 sheets or so) and put them into the input tray and then give some computer commands and the sheets of paper come out with information on them. Pure genius! And Staples made it all possible.
