At Prokraft we like something a little different and here is our tubeless single ended solid brass pen kit.
High quality solid brass fittings with the option of either a fountain pen (German iridium nib) or rollerball kit.
These are constructed differently to most pen kits and are great fun to make and also make a substantial pen at 13mm diameter.
Bushing are not required - these are solid brass and can have the finish of your blank applied to brass parts too.
The fountain pen will also accept standard ink cartridges but are NOT included
See below for our instruction guide or video
Wooden parts shown are NOT included
NB: The rollerball kit will accept both metal and nylon type rollerball refills
