A checkbook cover can be a great tool to protect the checks from any damage. You can put the checks inside by following a very easy process. They mostly resemble cardboard with a transparent strip of plastic. You can use your fingers to lift this transparent plastic. In the next step, slide the checkbook slowly into the gap that is created between the plastic and the cardboard. While doing this step, you can ensure to keep the checkbook containing your blank business checks or blank personal checks flushed with the cover.
