This was a gift. The advertising pages are only the first page and the last two pages; the rest is the same as a commercially available planner. More than half of the pages are blank, making it very easy to use, and it's thin, making it ideal for business. Because it doesn't easily close when opened, I think it's a well-bound planner.
