I've got a weird problem with my Waterman Expert Rollerball pen (https://jet.com/prod...63fa54fe31332d5) and Pilot G2 refills (https://www.amazon.c...uct/B004P3LW0U/). According to everything I've read on here and other places, the refills should fit just fine. However, the refill is loose inside the barrel. The nib (is that what it's called?) drops down about an eighth of an inch when I lift it off the page.
Are there two different sizes I'm not aware of? Has a piece fallen out of the pen that reinforces the refill? Am I just that dumb?
Thanks for any and all help!
