When should you use a gel ink rollerball?
A gel ink rollerball is ideal when you want smooth writing without applying pressure to the paper. The gel ensures an even ink flow that neither leaks nor skips, so your text always looks clear and professional. This makes gel ink rollerballs perfect for extended writing, taking notes and filling in forms.

Why choose a 0.6 mm line width?
The 0.6 mm tip offers the ideal balance between precision and visibility. This width is thick enough to make your text easy to read, yet not so broad that small letters become unclear. You can use it for everyday writing as well as for noting down details without the tip feeling too coarse.

Suitable for carbon copy forms
This gel ink rollerball is specifically suitable for writing through to copies. This means the ink contains enough pigment to press through carbon paper or self-copying forms. When you complete documents that automatically create copies for administration or archiving, this pen ensures that all copies remain equally legible.

Practical tip for use
Store gel ink rollerballs horizontally to keep the ink flow optimal. Thanks to the unique properties of gel ink, you don't need to apply any pressure while writing - let the pen do the work. This prevents hand fatigue during extensive writing and extends the life of the tip.
