What can I say? It's paper! I can write on it doodle draw put it through a printer or make an airplane and fly it across the room. It states it is acid free but I doubt anything I'm doing will last long enough for me to see if it yellows over time. All in all an excellent deal when you pick it up free and I do it each and every time it goes on special. I haven't had any jam in any of the printers faxes or copy machines it has been used in. I can't think of anything negative so I guess the lack of "cons" makes it good.
