Hi-Tec-C 04 Gel Ink Pen, Ultra Fine Point 0.4mm, Black Ink, LH-20C4, Value Set of 5

They are really smooth and perfect thickness for notes or drawing. I don’t have any problems with ink flow or the grip. Very good quality.

Simply put, these are still the best-in-class for job pens. Pentel recently ruined their Hybrid Technicas with a design flaw through the intention of no longer allowing their job pens to be refillable. Ironically, that redesign ruined the pen in multiple ways of actual performance (skipping, difficult flow) while retaining their premium price on it. However, Pilot retains their classic design and execution for the Tec-C series: The outcome is superb as always. The ink starts flowing as soon as the tip reaches paper with every stroke and maintains a consistent flow throughout. No skipping. You can make the line as fine as you wish with a curve or put down the full 0.4 thickness. Gravity is low, the grip is slender and comfortable, and, best of all, the gel container is replaceable with refills (if you're able to find them, the Coleto refills won't work here because they're designed for a multipen with a different shape). Pick this. You won't be disappointed.

Itty bitty writers unite

My favorite pens!!! I work in the medical field & we are funny about our pens..lol! If you are looking for extra extra fine, these are it!

Writes beautifully

This appears to either be a really good knock off or a different version of the pilot G Tec C4 that I have used in the past. Attaching a picture of my original one, and then the one I received. But they write very nicely and seem to be generous, with the amount of ink contained. So I’m not complaining. They will feel slightly different in your hand - slightly bigger it seems and a little bit heavier.

These are my favorite pens to write with! Haven't been able to find them in stores.

Fine, thin and smooth. Exactly for small writing.
