pens for the paper is too weak / thin, ink stains can be seen on the next sheet.
the notebook is very small, you can not feel good or not supported with the palm of your hand. So for a long time writing novels, or keep a diary that's nothing. For notes, it is sufficient, ok yes is also called notebook.
