This reams of paper are wrapped in paper and then covered in plastic. It is easy to crush the sides of the paper so that it doesn't slide into your computer printer easily. Also the moisture is easily entered. They should put this ream of paper in a box even though the plastic may be more cost effective. I see they run ads for free on this ream of paper. I really don't think I would take this item for free. I really wasn't satisfied with it. By the time I carried it to my car and into the office and it was snowing the moisture got into it.
We don't always print 11 x 17 but if you need it is better to buy the case. One ream is like $18 versus the whole case at $56. Defiantly worth it. Staples brand works just as good as the rest
