I often regularly use this paper for a multitude of uses such as copying various items (recipes newspaper articles etc) as well as printing the results of google searches aol news articles. While it isn't the highest quality paper it more often serves the many uses I have for it.
I have found some sheets that have wrinkles in them. When inspected these should be removed but were mixed in with the good sheets. Maybe it was a bad batch. Generally the sheets are good and wrinkles may not be a big deal unless you are using it for business and printing pages for clients where it needs to be a flawless sheet.
