, January 28, 2014
I purchased about a dozen of these ballpoint refills to use for my Uni Alpha Gel
pens, because my confidence in Uni and Mitsubishi inks was very high due to my
experience with the inks I used in their amazingly-designed refillable pens. But
unfortunately, I have had to throw the majority of my refills away due to
unacceptably poor ink quality and performance. The majority of refills I tested
were very slow to get flowing, with many occasional clumpy ink spots which
easily smear and transfer onto skin/surfaces and smudge the paper on which they
were written, inconsistent paper saturation, many skips - regardless of
handwriting pressure used, hardness of surfaces beneath paper, or pen design.
I even tested these refills outside of my pen, in order to rule out pen design
incompatibility and problems due to not distributing enough even pressure on the
ballpoint tips. Well, what a huge waste of time! Bottom line, I would NEVER buy
refills made by Mitsubishi again. These were not the only ones I purchased, I
also tried the exact same 1.4 mm ones in blue, and black and blues at 1 mm, with
the same poor results with all. Waste of my time, and way too much of a hassle!
I do not suggest purchasing Mitsubishi ballpoint refills, and for heaven's
sakes, I certainly don't recommend stocking up on a lot of them!
