Very smooth black lines. Definitely does NOT write like a 0.3mm. Closer to 0.7mm maybe. Just FYI in case you were thinking this would give you a fine line.

Of all the ink colors in this line, black is the smoothest I've used!
It does take some getting used to, but the tricks this pen can do are cool! Writes variable line widths, no skipping, smooth flowy ink, even when you write fast. Its not scratchy to me, and I am very picky about scratchiness (Hi-Tec C 0.25 mm, I'm looking at you!).
Writiing in English or Japanese (I can't write in any other languages but I'm sure it handles just the same) looks very pretty and you can even get a lttle fancy with your script uusing the Letter Pens, without even trying too hard.

Yes, you can use these refills alone without the pen body, but I suggest you get at least one pen body to try oout. I pprefer using the pen body not just the refill alone.

Bought this pen to practice chinese calligraphy, and I'm pretty disappointed. The pen writes very wet, causing the ink to feather and bleed on cheaper paper, or take a small eternity to dry on higher quality paper. The brush part is made of synthetic fiber and holds its shape surprisingly while still giving lots of nice variation. Unfortunately, it's also super thin and really really hard to control. I'll probably end up buying on the normal fine/extra fine refills next time.

This is a nice burgundy color, but it's a little too transparent to pass as real blood -- it's got a sort of watercolor quality to it. It's very close to the Marvy Uchida burgundy, but a little more transparent. It's roughly the same deep red with a hint of purple as partly-dry blood (not as red as freshly-spilled blood, not as brown as old dried blood) but not as opaque as real blood. (If that's your thing, you might want to try using an opaque acrylic paint instead.)

The Zig pens have a bit of a brush quality to them (with a small, mostly-stiff point) that gives a line quality similar to a Tradio/Pulaman/Fountain Pentel, but the Zig has many more color options. The Tradio/Pulaman/Fountain Pentels go "scratchity scratchity scratchity" when you write -- and sometimes "spit" little droplets in a random direction. The Zig writes more quietly, and has similar thicks and thins, but without the occasional spitty surprise. I personally prefer writing with the Tradio/Pulaman/Fountain Pentels, because their scratchiness grips the paper firmly and their ink is a bit darker, but I suspect most people will prefer the Zig's predictability and wider range of colors.

These are definitely my new favorite pens! Simple, sleek and inexpensive. I started with brown and have just gotten blue black and black. They write smooth and even better I love drawing with them. I actually use them in combination with copics and they don't smear. I haven't had any problems with blotches or dryness and for the amount of use they've been getting they still haven't run dry. The pen bodies are cute and feel comfortable to write with. Also, I definitely feel like they're better made than the Tradio Pentel pen body, which its plastic grip feels cheep. The only problem I've had so far is when I first got the black refill it needed a little dab of water to start running. Other than that an overall great pen!

Beautiful dark pink color!!!! Not going to lie, a bit pricey but thats my only complaint

I wouldn't quite call it blood red, it has a bit of a... mauve, maybe? tint to it. It's still a nice shade of red, and it writes beautifully. The super fine tip makes it easy to write very small, but you can also write a little bit thicker with it. Really looking forward to trying out more colors!

It's more like slightly dried blood than fresh, bright red blood. It's a little darker. The tip is a lot thinner and stiffer than I thought it'd be. When I opened this up, some of the ink had spilled in the cap a bit, but I guess that's normal... can't wait to start using this more though :)

The tip took a few paragraphs for me to get used to but now I love it. I think this will be my new favorite pen. The ink is smooth and doesn't bleed through. I bought this along with the pink body. I really like them both!

It took a while to get it writing at first, but now it's very nice! not too runny when I'm writing.

I do not like writing these the refill. are a little dry if you write fast, but the body of the pen is very comfortable and nice.

Almost scary how very much this ink looks like blood. There seemed to be a lot of ink in the cap on arrival (which I thought might have been due to Winter shipping) but looking at the pictures of the refills online, mine isn't noticeably drained after all.

If you like this pen or not will depend on how hard you press when you write. I find this pen overly stiff and difficult to write with if I use my normal writing style, but I have a very "light hand". The ink flow and writing look much better when I press much harder then I prefer. The description here is "Super Fine" and the package is marked "Extra Fine", and I am judging the line weight to be .5mm.

If you have a "heavy hand" and have broken .5mm pencil leads, this may be the pen for you. If you have a light hand like me, and have never broken even a .3mm "B" pencil lead and find that .25mm (000) technical pens write very smoothly, then don't bother with this pen.

I really wanted to like this gray refill but I can't get it to write with enough ink to be legible.

Would really help to have a pic of all the colors, since you now have quite a list.
Thanks for having so-o-oo-oo-oo-o many greate writing, drawing and drafting instruments available,
JetPens is the Best ! ! !

This is hands-down the smallest tip I've ever had the pleasure to use. It writes so finely, that I was able to write a poem of 107 words on a 2" post it note, with margins around the outside and between the paragraphs! I was amazed at the quality of the writing, with very smooth, dark ink. The pen "refill" itself handles just fine, but I used it with the Kuretake Zig Letter Pen CocoIro Pen Body - Light Blue, and it was really very pleasant. Definitely recommend for fine/small writing!

Pros: Nice fine line, lovely bluish dove grey ink. "Extra Fine" really is EF. I imagine it works great for writing characters with many detailed strokes.

Cons: These pens (well, refills, but I use them just as pens) tend to get blobs of ink on the tip while capped, no matter how they're stored. On some papers, they take an extremely long time to dry completely. I seem to be using up the ink very quickly, sketching rather than writing.

YMMV: The pen holders look weird with the refill sticking out the back. I'm not sure whether the blobbing problem has to do with something like the heat/pressure from using the refills without a holder. If I were more motivated to test them, I'd experiment, but I don't care for the holders and I like a narrow pen, and this is working well enough.

Overall: I love this soft grey for sketching and for fine, small writing, and it hasn't blobbed yet. It's functional enough to get a middle-of-the-road, 3-star review.

For me, there's no such thing as too fine a line. This is another super-fine pen to love. A little scratchy, a little dry, and the tip feels a little delicate--but no more than to be expected. The Kuretake Tegami Letter Pen super-fine refill edges this one out because it's smoother and less dry with easier line variation, even using rapid strokes (I don't have the Tegami nearby to compare, so I'm going from memory on this). But I like this one enough to pick up the black and the grey too. I'm enjoying it for intricate doodles and warmups, detailed crosshatching and small lettering. The sepia has maybe a little more grey in it than some variations on the colour.

Not waterproof!

I didn't purchase the holder (I think the way the refill pokes out the back is unattractive, except maybe for the "starry night with glitter" black holder, since it matches the glittery black ink reservoir), but I have no trouble using the refill alone as a pen. Larger hands may want the holder for convenience, and it does come in nifty colours.

This pen writes very nicely; I didn't buy the body so I just write with the refill and it's fine. The ink, however, runs out rather quickly and if i store the pen point down, it bleeds a lot (therefore wasting ink) so I just store it upside down. The colour is very nice and I love writing letters or writing small with this pen! It's a little pricey now but it's a good buy!

Really like it for fine details and lettering. May favorite is lime green color body. I got green and grey, 2 pens.

Nice color; it's usable for work. However, to get any variation in stroke width, you have to press down pretty hard and even then, it's not much of a difference. Pretty disappointed in that aspect. However, it is a good extra fine felt tip pen. You could just use the refill by itself, because it includes a cap.
