Is there a difference in rollerball refills like there is between the parker and cross ballpoint refills? I have a friend that has a Vertex magnetic rollerball and needs a refill. She would prefer to just go to a place like Staples than order from one of the pen suppliers. When I looked at Staples there seems to be variations on the theme again and I don't know which one to tell her to get.
