Product Overview
This 0.5 mm black rollerball kit is designed for use with Dave Dollar Freedom sections that accept the rollerball system.
The kit includes a smooth‑writing 0.5 mm black rollerball insert and a rollerball converter, so you can enjoy bottled fountain pen ink in a rollerball format.
It’s ideal for those who love the feel of fountain pen ink but prefer the convenience and control of a rollerball tip.
