I adore these for my bullet journal. I mostly use S (the smallest one), but occasionally branch out into the other ones. If I were to go back, I would just buy a bunch of the fine tipped ones. That being said, for some reason, my fine tipped one will sometimes decide that it doesn't want to give out ink which is generally weird, but overall, I love the way it looks on the page and the fact that it doesn't bleed!!!
