What sets the Signo Broad apart

Unlike standard ballpoint pens, the gel-ink formulation provides a wetter, smoother stroke that glides across paper without skipping. The blue-black ink combines the clarity of blue with the formality of black, making it suitable for both creative expression and professional documentation.

Ideal for...

Students taking lecture notes, office professionals signing documents, and hobbyists maintaining consistent journaling or sketching habits. The ergonomic grip is particularly beneficial for users who write for extended periods without discomfort.

Application of the Uni Uniball Signo Broad

1. Remove the cap and press the tip firmly against the paper
2. Write at a natural angle — the gel ink flows immediately on contact
3. Store the pen horizontally or capped to prevent ink drying
4. Refill with a standard Uniball gel-ink refill when ink runs low
