It's paper. You can write on it. You can draw on it. You can print on it. You can crumple it up for a package filler. You can make paper airplanes with it. It was on sale.
I always try to save the trees and conserve energy but sometimes there is not enough scrap papers (recycled back of junk mail back of flyers) to accomplish that. Staples® Multipurpose paper 8 1/2" x 11" Ream serves that need. And I always try to print on both sides of the page even though it takes more manual intervention. And don't forget the print draft mode so you can also conserve on the ink and toner cartridges. I also do black & white only to conserve on color ink or toner.
I am always picking up these reams as they are often on sale for next to nothing. Then I donate them to my son's school. The teachers and staff are always surprised when I had them some paper.
