We use these for our presentation books for our different clients, they are very easy to use and last a long time. they don't easily open up to let the pages in your books fall apart. Using this has helped us with our presentations and in turn makes our company look a lot more professional. The box it comes in is very accesible and easy to keep organized not to mention the value is great. We love to use them and recomend them to anybody that wants to put a presentation together and make a great impression. You will not be disappointed.
