Good quality paper. I use it for all documents I give to my clients including letters. It does not bleed through and has higher quality feel and look to it than regular paper which my clients have come to appreciate.
I like this 22 lb paper. It has a much nicer feel than standard 20 lb and the 98 bright looks better than the 92 bright which has a yellow tinge to it. It is more expensive (of course) but Staples puts it on sale periodically and my printing volume isn't large enough to make it a significant extra cost.
