One Change

The refillable One Change Rollerball with the exchangeable One Change cartridge ensures the best writing experience thanks to its Ultra-Smooth tip.
With a line width of approx. 0.6 mm, the One Change is indelible and waterproof according to ink standard ISO 14145-2. The innovative Super-Flow-System guarantees consistent ink flow from start to finish. The cap-off ink does not run dry even if the cap is removed for 2-3 days and, besides this, is quick-drying and smudge proof.
The One Change has a sturdy metal clip and a rubberised grip zone that provides a secure hold for relaxed writing. One Change is manufactured in a climate-neutral way.
