This is quite a nice waterbrush. I originally got it because of its two-part
design -- it's really convenient and fits into my travel paint boxes. The brush
itself is well made and comfortable, and can produce a variety of strokes. The
only drawback is the small water capacity -- depending on how wet you work your
paints, you might run out before the end of a piece. But I always carry extra
water when sketching outdoors, so this hasn't been an issue.
This is a wonderful drawing tool. My first brush pen was the Pentel Pocket one,
and it is a lovely pen. But this Kuretake has a higher quality brush with more
spring and a finer point. I am really enjoying it.
Just fyi, I use Platinum Carbon ink cartridges instead of the supplied ink,
because the Platinum ink is waterproof and dries near instantly on most papers.
Happily the Platinum and Kuretake cartridges are identical to each other (even
down to the little metal ball), and the Platinum converter fits this pen
beautifully as well. I've had absolutely no problems with inkflow.
This is a follow-up to my review on August 12th. I have used this pen daily for
weeks now, and it's become my favorite inking pen. However, it did act up on me
once. The ink flow stuttered when I drew fine horizontal lines or when beginning
a stroke. I fidgeted a bit and I found that there is a pad of some sort of fiber
directly under the steel nib. If that fiber pad gets a little dried out, you'll
have ink flow problems. I think this is why they recommend you not leave the pen
unused for more than two weeks. (The ink dries very quickly, which is good when
you're drawing, but problematic for pen storage.)
If you're getting spotty ink flow, another reviewer suggested that you give the
nib a quick rinse in warm water, which works well to rehydrate the ink pad.
However, it does dilute the ink, so you need to scribble a bit to get full
strength ink flowing again. What I do instead is put a drop of black ink (I use
black technical pen ink, but you could use a drop of any black fountain pen ink)
onto the little air hole on the nib, and let it soak in for a few seconds. This
restores the ink flow perfectly without dilution, and the pen is ready to draw.
No skips or stutters.
And a final note about the ink: this stuff is as black as anything I've ever
used, including black India ink in dip pens. It dries very quickly, even on
shiny surfaces like bristol board. And it is -very- waterproof. I use
watercolors with my pen drawing, and I don't have any problems with ink running
I purchased this pen after I recently bought the 0.3mm Linemarker. The 0.3 made
a line roughly the width of my 0.5 gel pens. Therefore, I expected this pen to
make a finer line, perhaps close to 0.4 or even 0.3 gel pens. Unfortunately, I
cannot see any difference between the two pens. I've tried both of them on all
types of paper, and the results are visually the same. I compared the nibs under
a magnifier, and didn't see any size difference between them. So I'm
disappointed. Like the 0.3 pen, it makes a nice consistent line on most papers.
(It skipped a bit on rough sketch paper.)
This is a really magnificent ink. The color is a dark fuschia when wet, and then
it dries to a deep rich warm purple. It's actually more conservative in person
than how the sample appeared on my computer monitor. But I like that. It means I
can use this ink in business settings where a bright, garish purple would raise
And, as everyone else has commented, this ink performs beautifully in every pen
This pen writes smoothly and produces a consistent line without skipping. The
ink is a nice deep black that dries quickly, and does not smear when I go over
the outlines with watercolors. But the line is heavier than I expected. The 0.3
mm nib produces a line that is roughly the same size as my 0.5mm gel pens. It's
still quite useful, but I've now ordered the 0.1mm pen to do the fine detail
that I'm working on.
The Linemarker reminds me a bit of my old rapidograph technical pen and their
dark, consistent lines. But rapidographs were scratchy, even on smooth paper,
and the ink flow was always a little finicky. In contrast, this pen writes
smoothly as soon as you remove the cap, without shaking or figiting.
Yes, it's a specialized pen, and I don't think it would be comfortable for
extensive writing sessions. (I'd suggest the Hi-Tec-C .25mm for that.) But I
needed something this fine for annotations and small details in my sketchbooks.
This pen has performed beautifully for three years now, on a variety of papers.
A big plus for me is that the ink is absolutely waterproof, unlike the
Hi-Tec-C's. So I can go over my drawings with watercolors without any fear of
the color running.
I have been using this pen for about three weeks now, and I am really enjoying
it. The ink flow is wonderful, and the slight flexibility of the nib brings
subtle expressiveness on the lines. I have used it on a variety of papers, and
it's been particularly nice on smooth Bristol and hot press watercolor. I draw
with a light hand and rarely notice any scratchiness.
The nib on this pen is somewhat flexible, which allows you to vary the width of
the line depending on the amount of pressure you use. I've been using it to
sketch for the past few days, and I'm impressed with the inkflow (quite fluid)
and the smooth feel on paper. It is worth noting that it does better on "hard"
papers like Bristol board and layout/marker bond. I also tried it on softer
finish papers, like sketch and drawing pads, and it felt a bit dry and scratchy.
Definitely with the price.
