Its medium-fine tip delivers consistent, precise lines suitable for forms and detailed handwriting. The pen is compatible with standard ballpoint refills and features a pocket-friendly design for convenient carry and storage.

Advantages

The click mechanism allows one-handed operation and quick retraction of the tip, reducing the risk of ink drying or accidental marks.

How to use
