Our refillable rollerball nibs can be used to make custom, or so called kitless rollerball pens, and are fitted into a sectiion in just the same way as a fountain pen nib housing is fitted.
We have thread taps to facilitate the internal threading of the rollerball section, made specially for us from M2 HSS steel by TapCo, the globally acclaimed precision thread cutting specialists. They are available individually - starter, intermediate and plug (bottoming) or as a money saving set of three.
These taps are also compatible with Jowo, Schmidt and Heritance size 5 fountain pen nibs.
If you need a hand deciding what you need, feel free to get in touch - we are more than happy to help.
