Will a rollerball or gel fit?

[DocStram]

Will a rollerball or gel refill fit in a cigar?
What else will a rollerball fit in?

(I know we've talked about this before, I just can't seem to find it)

There are gel refills that match the Parker style refills.

RB, as far as I know won't fit. I do use the gel parker type refills on them. I buy my refills from CSUSA...can't seem to find a cheaper/better source for it.
