I purchased Staples Multipurpose Paper in a 5 ream case to take advantage of an amazing rebate deal and didn't really expect the quality of this paper to be as good as it is. Even though it is the standard 20 weight paper it seems heavier than that and it must be due to the whiteness of it which is rated "96 Bright." The Staples Brand exceeded my expectations for a multipurpose paper and I am very pleased about that because since I bought five reams I will be using it for a very long time!
