I got this ruler because I needed a short ruler to make lines in my bullet journal to draw. I love that this ruler fits nicely in my journal's back pocket, that it's stiff and thick enough to be easy to handle, and that it's transparent so I can see through what's going on while drawing lines on what I have already written helps. on the. I also appreciate that it comes in a 3 pack because my cat tends to nibble on things and it's always a good idea for me to have spares.
