I'd liked to convert my Montblanc rollerball into a gel ball. I like
the rollerball, but I like gel balls even better. Is there a gel
refill that fits a Montblanc rollerball?

Take refill of Pilot G-2. Remove that cap from its other end. Shorten
that translucent tube and put that cap back back to that open end.
