Hello, At 4:40 in this video, you will see a rollerball pen that is angled to mimic a fountain pen nib for people who hold their pens a lot to the side and not so upright (I fall into that category). https://www.youtube.com/watch?feature=player_detailpage&v=SveKuIxBKBo#t=277 Where in the world can I buy such an exotic rollerball tip? Do any modern makers produce these? Lastly, do they exist in different angle variations?
