I have the L05EF (Extra Fine), which I got here at JetPens, so I want to share a
cautionary tale about this family. Just as another reviewer, I'm having serious
leaking issues with this pen, the first cartridge went fine, the Extra Fine line
is actually like a gel pen medium (0.7), but it wrote soft and didn't skip, then
I used another cartridge and a drop of ink was always over the nib, this
happened with a few of other cartridges, then the second to last cartridge I
installed, and after a week or so of no use, the ink leaked from the middle of
the pen. I throughly cleaned the pen and installed another cartridge, and after
a few days I opened the bottom of the pen to check how it handled, and there was
ink all over the place, luckily, even when the bottom has a plastic cap with
small slots, none of the ink got through there and onto my notebook.
I'm so sad because for about two years this was my go-to pen at my desk, but it
seems I can't use it anymore. I will give it another chance after my new Kaweco
runs out of ink to see what happens.
Weird thing is that I have a Safari with what I guess is the same nib mechanism,
and it runs fine.
TLDR: Loved it when it worked, now it leaks like an open faucet.
