OHTO Graphic Liner Needle Point Drawing Pen (CFR-150GL005), 5

This I got for a gift for my dad and he enjoys using it very much, this is very special to him because of the fine line it writes and what you can use it on

Paks of one size nib would be helpful.

I can be pretty anal about what writing utensils I use, particularly for my art journal. The pen writes over watercolor well. It skips occasionally, but doesn't bleed, and I like it a lot.

I enjoy writing with very fine-tipped pens, so this was a treat for me. I first heard of OHTO from Massdrop, and I had tried their fountain pen and their magnetic capped pens, both of which I enjoyed using. I saw a set of their Graphic Liner pens with various thicknesses, from 005 to 10. I decided to buy more 005 variants.They were very smooth for writing and write very finely, but there is one thing that causes me to give it a 3 out of 5 instead of a 5. When exposed to even some heat, these pens will leak ink. Once it starts leaking ink, there is no going back. They will leak ink to the point where they spew ink if left in too warm of an environment. I have lost all 3 of my 005 graphic liner pens due to this.

Got one of these pens from a coworker and it's my current favorite, surpassing the Pilot Hi-Tec Maica and some Mujis that I normally use.

Lines weights are inconsistent and now it leaks from above the nib in spurts. Not sure if it's a build quality issue or I just got a bad one.

These aren't bad pens, but you kind of need to know what you're getting. I actually picked them up via Massdrop; I'd never heard of them before, and got a dozen of these .005.The tips are metal somewhere between a typical pigment liner (micron, staedtler, or copic) and a ballpoint pen. The line quality varies more than those pens, depending on the angle and speed that you draw with, but its very possible to get thin feathery lines (like hatching) in a consistent manner. I had no problems controlling the line quality, once I'd gotten familiar with it.Paper makes a big difference. Because these have the metal needle-tip, they seem to do much better on higher quality, heavier weight paper. I did not like using them on thinner copy type paper, newsprint\tracing paper, or on toothy cold press. If the paper is soft and\or thick, you need to be very light on the touch to avoid scoring it. These bleed very slightly on super thin paper. I had no problems on the paper I was using with smearing, but depending on the paper and the tip thickness that could be an issue.Overall, I'm pretty happy with the pens. I still primarily use my existing mainstays, but these filled a gap nicely, and have become regular hatching\shading pens.

The greatest writing pen for this price point ever! I adore this pen.
