Way too thick for being a 2 ink plus mechanical pencil, Zebra could have
squeezed everything in a slimmer chassis, I know they can because I have a Zebra
Sharbo which includes a more complicated mechanism inside. The Uni-ball Signo
MF3 is a better design. However, the mechanics and ink quality are top notch for
As I have been testing the waters and going from gel inks to fountain pens, I
always get surprised when I don't the extra fine line I was imagining. Even
compared to other fountain pens, the line is way thicker in this extra fine nib
than other pens. But I'm getting used to it. The pen looks great, the screw-in
cap is a great idea for a fountain pen and paired with a Diamine ink, works
great. It is a very small pen though, and I have big hands, so I always need to
use the cap on the back to write comfortably.
I learned about this ink in a blog entry of JetPens, and I knew I had to buy it!
As soon as some of my ink reserves went down, so after a year or so I got this
small pack and have been using it with a Kaweco Sport. I really like this ink,
is a space deep pitch black, really strong and dark hue, dries fast, and looks
I have the L05EF (Extra Fine), which I got here at JetPens, so I want to share a
cautionary tale about this family. Just as another reviewer, I'm having serious
leaking issues with this pen, the first cartridge went fine, the Extra Fine line
is actually like a gel pen medium (0.7), but it wrote soft and didn't skip, then
I used another cartridge and a drop of ink was always over the nib, this
happened with a few of other cartridges, then the second to last cartridge I
installed, and after a week or so of no use, the ink leaked from the middle of
the pen. I throughly cleaned the pen and installed another cartridge, and after
a few days I opened the bottom of the pen to check how it handled, and there was
ink all over the place, luckily, even when the bottom has a plastic cap with
small slots, none of the ink got through there and onto my notebook.
I'm so sad because for about two years this was my go-to pen at my desk, but it
seems I can't use it anymore. I will give it another chance after my new Kaweco
runs out of ink to see what happens.
Weird thing is that I have a Safari with what I guess is the same nib mechanism,
and it runs fine.
TLDR: Loved it when it worked, now it leaks like an open faucet.
An expensive accessory but once I had it on my hands I knew why.
First, note that it works with pencils with a length of up to 10cm. Unless you
want to have a protruding and large pencil.
The pencil is secured with a mechanism similar to those used in a drill to
secure drill bits, and the eraser uses a screw top system too, you turn it
clockwise to show the eraser little by little, very sophisticated.
And of course, it is lightweight, it might add just the required weight to a
wooden pencil to convert it into a balanced writing utensil. Very useful to
write comfortably with the last bits of those pencils laying around the house.
Very hard on the paper and light lines. It is biased towards an H grade lead, I
prefer leads that feel hard and won't break but that will write softly and with
dark lines. My personal favorite are the Uni Nano Dia leads.
Standard cheap case with only 12 leads. Very expensive for what it provides. I
really like Lamy products (Those were my introduction to the world of pens), but
these leads disappointed me.
A bit thinner than expected from a 0.4mm line, and it scratches the paper.
Sometimes it skips. The form factor is the same as other models from Uni (Signo)
and Pilot (Hi-Tec) with a rubber grip. I would recommend the other brands.
Interesting novelty item, gave it away as a gift but not before having a
demonstration. Effectively staples securely about three pages without much
effort, and those kept hold together in an impressive way.
Soft on the paper, but seems to be a hard lead, well balanced just like expected
from an HB lead. The case opens with a small half twist around an helical ridge,
just like a screw. The case cap has a small dent that helps to prevent the case
to roll and fall. Works great on the Kuru Toga, but, well, almost all leads do.
Great compass, metal construction and the addition of a mechanical pencil makes
it even better. Would have loved to have one twenty years ago in the math
lessons. But from time to time I still need to draw a circle, so, here it is the
tool for that.
