Ceramic pens are a classic for any pen lover. The pen writes with a smooth yet sharp feeling that you can't get with some other gel pens. This nicely designed ceramic roller ball pen refill by Ohto is available in four sizes: 0.4 mm, 0.5 mm, 0.7 mm and 1.0 mm. It comes in multliple colors and a standard body size so it may fit other ceramic roller ball pens.
After trying the 0.5 black, blue, and the 0.4 blue, this refill for the Ohto
Ceramic pens is my favorite. The flow is constant and rich, and the color is
fantastic. It looks larger than a normal 0.5 pen, but I've learned to love it!
The only thing I've noticed is that they run out fairly fast compared to other
inks. But it's well worth it!
Tried two of these refills after my original black cartridge started skipping,
and after a few days, both of these started skipping too. I need to find
something else to use with my Tasche, as i love the pen design but without a
reliable refill, it's worthless. really like these when they work, but I think
there must be a problem with manufacturing at the moment.
