I’ve had various color combinations of the Pilot Kakuno languishing on my JetPens wishlist for a while, but it took being stuck home sick in a syrupy haze of cough suppressants for me to actually decide to order one. Which I ordered from my Amazon Prime, for whatever reason.
Although I picked everything about this pen based on what option was cheapest on Amazon at the time, I like the dark grey and lime green combo. The color is fun without feeling childish. Not that there’s anything wrong with childish—this is designed to be a kid’s pen. But the design isn’t aggressively elementary school; it’s a minimalism that holds a broad appeal.
There’s no clip, but the Kakuno is hexagonal and the cap has an unobtrusive little nub to help discourage the pen from rolling away. The grip is shaped in a roughly triangular hexagon, with all edges (if you can even call them that) quite rounded—the guidance from the grip is subtle and comfortable. The pen itself is lightweight, yet the plastic feels reassuringly sturdy, as far as this price point goes. It’s no luxury resin, but it’s also not some cheap, fragile crap.
Here’s the most unavoidably adorable part: the face of the nib. Literally. A smiley. face. (unless you have one of the soft body colors; then it’s a winky face) — it’s another point of guidance for the novice fountain pen user: if the pen is smiling at you, then you’re holding it right (or at least not upside down). Maybe not everyone is confident enough in their adulthood to rock out such a happy pen on a regular basis. I’m not here to judge you. But it’s really only noticeable to others if you point the face out. Or if they stare at your hands obsessively.

For example, if your hands were on fire or something, that might draw extra attention to the vicinity of the happy nib
To be on the safe side, I probably wouldn’t take this pen as my prime writer in a Serious and Professional Meeting of Important Business, but right now it’s my favorite no-worry knockabout pen. I toted it around on a trip to the mountains. I’ve thrown it in countless bags, back pockets, and cup holders. It writes reliably, neither too wet nor too dry, and the fine nib is perfect for everyday use. The performance of the nib itself was surprisingly pleasant (not sure why I was surprised, I should have known Pilot wouldn’t let me down), a sort of tactile feel on the page without any scratchiness or sharp edges.
If you’re looking for a specific color or nib size, JetPens has the full selection. If you’re looking to save a few bucks and aren’t picky, you can likely find a Kakuno on Amazon for under $10 (right now, the winning combination is a fine nib White Body Soft Blue cap with free Prime shipping, clocking in currently at $9.46).
