I met plenty of productive people who do so with hardback notebooks and a pencil, you are good. Other thing I saw is once they are done with it they glue a paper on the cover and notedown some things and throw the notebook in a big plastic box for archival. Recently finished notebooks tend to find some time living in their desks before going into the box.
