I was actually a bit surprised how much I like this pen. It's one of the
smaller pens I own, but sits well in the hand. The roller ball writes very
smoothly and with an agreeable line thickness. One very small disappointment is
that the pen does not lend well to being converted to an eye-dropper filled pen
in part because of there how far down the barrel the cap reaches (won't go over
an o-ring), and partly because of how deep the nib threads are within the
barrel. Nonetheless I made the conversion using only silicon grease for
sealing, and will test it out. Otherwise, extremely pleased with the pen.
I love these pens. I love that I can use any kind of cartridge fountain pen ink
- or using a converter, I can use bottled fountain pen ink as well. The sky's
the limit for color choices! I like that I can use them on multi-part forms
like a ballpoint. I have used them for years and had only 1 that after a few
years of daily use, had a problem that the ball didn't roll. I have switched to
a lubricating fountain pen ink and it is writing again. I think they are a very
I had high hopes for this pen, but it is a huge disappointment. The roller
doesn't start laying ink right away, especially at the beginning of upstrokes,
so I keep having to go back and write over my words to correct the missing
parts. I wouldn't buy this pen again.
I love the Kaweco rollerball pens! I love being able to use just about any
fountain pen ink so I can write in any color I want. Since you can also get a
converter, the sky's the limit! The line is very smooth and it is great to have
a ballpoint so you can write on multipart forms and the point doesn't dry out as
quickly as a fountain pen. Great product!
I've been pleased with my Kaweco roller ball after several months of ownership.
As I use mine almost every day I found after slight skipping with the first two
cartridges an instrument that writes quite well with unusual exception in the
value price category. It is an attention getter as well. Most people have not
seen a pen like this and it catches their eye often prompting questions or
requests for a closer look. I did purchase the nickel pocket clip with this
pen. I enjoy writing with it very much, the range of color choices, and its
roller ball point as I have a heavy hand. It's been worth every penny.
