Every pen model that you see on my website can be made into a rollerball if the customer wishes. Below are examples of some models as a rollerballs.
These rollerball sections will fit into my fountain pen bodies. So if you wanted to buy a fountain pen that would have an extra rollerball section, this is no problem. If you wanted to have a rollerball section to add to an existing Edison Fountain Pen, no problem, in most cases.
This also makes a great gift idea for a pen enthusiast who is not familiar with Fountain Pens. A pen could be made with both a fountian pen and rollerball section, and they could be interchanged.
Email me to inquire.
