Very nice ink- like a gel, no skips or globs- everything that's good about the
best-functioning jetstream inks. The color is neat and a bit different from
other purples- dark, but with a sort of plummy hue more than blue. The most
important and wonderful thing about this refill, however, is that it works with
the Uni Alpha Gel Shaka Ballpoint Pen! I love that pen body, but the ink
included is unremarkable, and no Uniball Jetstream, Pilot Acroball, or Zebra
Surari refills work with it. (I tried.) Now that I can put a better refill in, I
will be using that pen much more.
