Rollerball Conversion Kit flourish and refilled for a lifetimeSometimes you just fancy a different kind of glide. This Rollerball Conversion Kit swaps your Studio Fountain Pen's nib unit for a smooth rollerball mechanism, so the same pen you already own can write two completely different ways. No new pen to buy, no tools needed just unscrew your nib unit and twist the rollerball mechanism in. Switch back to fountain pen writing whenever the mood (or the ink) takes you.
