This review is long overdue. I took almost one year of writing with my Kakuno before writing this, not because I didn't want to do this review or forgot about it, but because I truly didn't know what to write.

Pilot is known for the quality of their products for office and their high end pens, but not so much for their children's focused products, so I was highly unsure of what to expect when I bought my Kakuno.

The nib is Japanese extra fine, which means, the finest fine isn't fine enough to describe how fine this nib is, but unlike my expectations told me would happen, this pen glides over the paper, butter smooth like very few pens I've owned over the years (yes, it includes ballpoints and rollerballs in this list). It sure is far away from being anywhere near wet too, maybe the medium or broad will be, but seeing from the extra fine, I can almost be sure the fine nib will be equally dry.

The triangular grip takes a little getting used to when one isn't used to it, but it's very comfortable and in no time it feels natural to just hold the pen like it guides you to do. It doesn't have any sharp edges and the area near the nib has a small and comfortable slightly rounded stop so the fingers doesn't slip down.

The hexagonal body prevents the pen from rolling everywhere and the cap, when posted, makes it even harder to happen.

Only thing this pen misses is a clip, but, in my sincerest opinion, one doesn't even miss it if they think that this pen is supposed to be carried in a pencilcase to school.

This is a well deserved five stars!

I like the clear demo barrel for this fountain pen. This extra fine nib have some flex to it and it could be the ink I'm using that it actually flows more than the fine nib which writes with very thin to thick lines. To save from throwing away the plastic cartridge when empty, I just inject my favorite iroshizuku ink with a syringe.

The thinnest line you can get on the best starter fountain pen! The Kakuno is a solid pen: lightweight and comfortable with a slight hexagonal barrel. The cap clicks on tightly and posts well. The only thing missing is the clip, though it has a tiny ledge to keep it from rolling away. The Japanese extra fine nib has some feedback which is to be expected but it writes very well with no skipping at all. Although personally I prefer the fine nib since it's smoother while still providing very thin lines, I am pleased as punch with this pen and especially love that it comes in a clear version!

I really like this pen. Holding up well. I've left it in my car on very hot days and no leaking or burping. I don't know how many times I've dropped it on to hard floors. Fortunately not on the nib.
Light weight.
No skips.
Hasn't dried out after two weeks of non-use.
The cap fits tight.
Posts well.
No clip is not a problem for me.

My one reservation is that I forgot how fine the Japaneses nibs are. I may have to get another with a fine nib.
I like this pen.

This cheap plastic pen is way better than my other expensive pens that I owned. It can even handle frickin' Noodler's ink on those crappy notebooks u get from Walmart during back to school. On cheap copy paper no bleed through and no feathering. Buff the thickness to 28 lb and u won't see it on the other side.

Nib size is small and gives a nice scratchy noise when writing, very satisfying. Flushing is simple and easy. Just take it all apart and clean it. The transparency is gorgeous. U can write without posting, but posting will make it a lot better and u don't loose the cap. Very sturdy and won't break unless u really want it to.

I'm guessing the reason why this pen is soo good 'cause they made it for kids, and we all know how good they are at destroying things.
