This is paper. It is advertised that it will not yellow or crumble over time. Well I can't say that it will or won't as I haven't used it that long. It is a white white an produces very readable copy. It is great for copy and everyday use and that is what I use it for. For legal documents I prefer a heavier paper with greater percentage of cotton. Never have a jamming problem. Cost was reasonable because I bought it with a special deal. Paper is becoming very expensive so purchasing when the paper is on sale seems worth it especially if you have a place to store it.
Staple's multipurpose paper works in all our copiers without any problems. Very few paper jams or other issues. I rate it as good as the more expensive brand name paper. Thank you for a superior product and thank you for the great price. I will be back to buy more of this product in the future and will pass on the information to my friends and other co-workers.
