Collapsible ones are extremely practical as you also get many extra functions in the bargain with, for example, degrees. The fact that they are also easy to carry in a pocket on a notebook, in a pencil case or standing in a pencil cup without being in the way is another plus. Then we have partly in a folding ruler in plastic and also in a more durable material such as aluminium.
There is also a smart model where a plastic ruler is combined with index tabs, quick marking in a book.
In addition, there is a wide range of rulers that are really decorative. Partly in combination with a stencil but also with a clip. Nice way to mark where you are in the book. It is worth mentioning that there is a more pared-down variant that aims primarily at the clip function and with a ruler.
For finally affordable and cheap in plastic and a model with a stencil with the sights set on Bullet Journaling.
With us, as I said, you will mainly find smart models that are practical to have in notebooks or pencil cases. Always ready to have at hand!
