I sold a Jr. Gent ballpoint today and the customer really liked the Jr. Statesman Rollerball. The only thing is he wants a larger nib assymbly (diameter)so that it will fit his hand better. I don't think he would be against a different kit of some sort, but what are my options. Do I need to make a regular Statesman or is there a kit that has a more robust nib assymbly? Thanks.
