Push the cat's tail to click; skinny barrel; immense joy; first S of the video

Looks office-bland but thick, wet, juicy stroke; sleeper hit; great signature

Great click, good flow, precise needle tip; more control than Muji; ugly but daily-driver worthy

Awful to write with but iconic; earned S for classic status, not quality

His jam; right barrel size, good grip/clip, ink not too wet; straight to S without writing

World favorite / cult following; wet ink, good click; S because it can't not be

Most useful Micron size for drawing/writing; goated; S immediately

Pull-off cap, EF writes great despite looking fat; wireframe clip; budget color options; goated

Unbelievable for the price; crispy fine point; pull-off click; light clear body; easy fill; beginner S

His favorite fountain pen overall; ~$30–35 US; prefers even to Montblanc 149 in some cases

Old reliable; almost cuts into paper; everyday-carry classic; A not S because he likes other Mujis more

Rips; hinged pocket clip; moderate click; stormtrooper matte-white aesthetic


Surgical crisp lines; immediately dry; shows handwriting imperfections (helps him improve); revisited at 17:13, still A

Bold/dark like a Sharpie; pronounced click; good grip; some bounce; wishes it were finer

Almost like a mechanical pencil; lovely but maybe too fine; A for sure

Great size like Sport; brass a bit heavy over time; prefers acrylic version if available

Handy for habit trackers/color boxes; slide lacks authority; fat barrel; forgettable otherwise


Fun ink, writes well; medium not his preference but decent for M; B

Crispy flow; low-profile; what it needs to be; no gimmicks — B

Looks promising (matte/DLC vibe, cool clip, good grip) but flow lacks soul; biggest letdown; B for finish
Great click; hexagonal (won't roll); nicely made but he doesn't miss it — B
Instant D; packaging joke energy



Most expensive in video; too much spring kickback; filthy roller; criminal at $50 — absolute D
Heavy knockoff; gutless roller feel; cheap clip/milling; offensive — D or lower
