Not suitable for small font size

Looking for a couple of colorful pencils in order to in lectures can make sketches etc. clearer, I came across the write poles offered here.
Positive to be highlighted is the quasi non-existent resistance when writing on paper. The colors are also very pretty strong. Furthermore, the pins dry very quickly and make a smear thus highly unlikely.

So why do I give only 3 stars? The answer lies in the possible font size: In order to produce reasonably legible letters it is inevitable, about twice the size of writing, such as a ballpoint pen.
This phenomenon is not occurred to me when other gel pens.

Due to the last-named, I will in the future probably again switch to Fineliner, even if they can not play as strong colors.
