This is an excellent quality paper for copying and printing )either one or both sides). It is durable and the bright white has a professional look to it. I have used this paper for all of my personal and professional work. No one can tell that this is not a highly over-priced paper from some other "big name" manufacturer. I highly recommend this paper for anyone who must print out a presentation proposal or draft of an article. I have sent many professional proposals and publication drafts using this paper.
