All I can say is this Staples multipurpose paper is excellent. Its bright white doesn't curl never jams in my printer. I use it all the time. The price is excellent as well. And you get the added bonus when you get the Staples rebate. Can't say much more. Its all good.
Paper stays bright even if I use it in the laser printer. It offers durable construction which keeps the ink from seeping thru. And when I am finished it folds crisply in the envelope.
