Excellent refill. Uni-ball Signo ink is put into the ballpoint. Note that, Signo
ink contains check fraud protection, as per Uni-ball's website. I submerged a
sheet of paper with a written sample in alcohol, bleach, and boiling hot water:
the tests passed and the ink remained. We need D1 refills now. Smooth writers
Excellent refill. Uni-ball Jetstream ink is put into the ballpoint. Note that,
Jetstream ink contains check fraud protection without ISO 12757-2 certification,
as per Uni-ball's website. I submerged a sheet of paper with a written sample
in alcohol, bleach, and boiling hot water: the tests passed and the ink
remained. We need D1 refills now.
My favorite gel ink. Already tried the Hi-Tec-C, Sarasa, and Sharbo X gel inks.
The Uni-ball Style Fit refills own all of them. Excellent and smooth enough for
left-handed writers with vibrant colors. The inks passed my water-resistant test
of running hot water over written paper. Now Uni-ball needs to create D1 refills
with this ink so we can use them in the Sharbo X multi-pens. Hurry.
This is the converter to get if you own those rare coveted Rotring 600 and 900
series fountain pens. Seals tight with section and no leaking. The red ring you
see on the converter by the way, is part of the rubber stopper at the end of the
piston; it is not a red ring printed on the plastic body, as Rotring typically
has characterized on its pens.
Nice color and good quality. However, it's not very left-hand friendly. It
writes smoother 'away from the paper' to accommodate a right-handed person.
Dries faster and more water resistant than the Hi-Tec-C ink.
A nice quality refill. Tried it to get the Hi-Tec-C experience in a Sharbo X
multipen. Unfortunately, it's too loose and won't fit snug. The refill will fall
out of the pen if your try to use it. A remedy was to put a small piece (2mm
long) )of scotch tape on the top of the refill, and it will fit with friction.
The ink is not as good as the Sharbo X refills (not as water-resistant), but
will be smoother to left-handed writers.
Excellent multi-pen. My favorite and quite possibly the most beautiful and
durable of the Zebra Sharbo X line. The inner turning mechanism and inner parts
of the cap are metal not plastic, unlike some Sharbo X models (like AL5 or
The clip has a spring in it, but you must 'raise' the clip from the bottom, not
by the top like a conventional spring-loaded clip (the 'premium' TS10 line can
The thin, shiny black upper trim of the barrel (right above the carbon fiber
part and below the "Sharbo X" white printing) can peel if there is a collision
with a hard surface, so exercise some care if you want to avoid this.
The carbon fiber wraps around the barrel made of aluminum; it's not the main
constituent. If you look inside the barrel, there is shiny aluminum, not carbon
fiber, so you cannot take advantage of carbon fiber's lightweight properties.
This pen will accommodate other D1-sized refills, not just the Sharbo X refills.
I've loaded this pen with Space Pen SU series refills. Lamy M21 refills will
Looking at it, quite a beautiful pen. This graphite version is the one I own.
However, given the price point, it important future buyers be aware of certain
aspects of this pen. The shiny clip, barrel tip, and cap are prone to
scratching. I did my best to store and take good care of it, but to no avail: a
long linear scratch formed on the clip, and little scratches on the barrel.
Do not drop this pen on hard surfaces, as it can slightly form a dent at the
site of impact. The graphite paint can chip as well. It is recommended that this
pen be stored in its own pocket or sheath. Avoid tossing it into the pencil cup
with your other writing implements.
Also, compared to its sturdier/cheaper CB8 and LT3 variants, there is a
deficiency with the mechanical pencil component. If you are using it, always
retract the lead before turning the pen to an ink component. If you don't, the
turning mechanism will get stuck, forcing you to unscrew the barrel and manually
retract the lead in the pencil component. This is because there is limited room
in the barrel tip due to its shape with *four* components (3-ink + pencil)
crammed in there. I also own CB8, AL5, and LT3 versions of this multi-pen, and
lead retraction is not necessary in these versions.
For the price, I expected a more sturdy, robust, and durable pen, not one where
even meticulous care won't guarantee it will remain in good condition.
