The fine tip works good for outlining small areas when coloring, or for writing in my journal although at times I find that if I write too quickly (as I would with a standard ball-point pen) the ink from the fine tip doesn't seem to flow quite fast enough and sometimes it will skip or leave an extremely light mark

They're good for bigger items, but not for any sort of fine work

The super fine end is cool for fine detail work, but I probably won’t buy these again.

The "big" end is still on the small side but works perfect for smaller projects like planners or bullet journaling.
