In this video, I go full hyperfocus mode and answer the big question: what actually makes a pocket fountain pen a “pocket” pen—and which one is the best in 2025? I pulled out my pocket pen collection (19 different pens, not even counting colorways) and broke everything down with practical definitions first: capped vs uncapped vs posted, because pocket pens live and die by how they feel once they’re posted. From there, I walk through my best picks by “type of pen person,” not just by price. I talk about the best pocket pen for huge ink capacity, the iconic EDC-style pocket pens, and the fancy princess pocket pens (yes, that’s a real category in my brain). I also compare pocket pen lengths against pocket journals, explain why you might want a pocket pen in the first place, and highlight some truly unique engineering—plus hard-to-find options, easy-to-buy options, and the wild one that’s literally made with milk. I end with my general thoughts on how to choose the best pocket fountain pen for you, because honestly, “best” depends on your hands, your paper, and your daily carry life.
