Ballpoint Pen Berlingo TRAINGLE FUZE RT 0.7 mm, triangular barrel, blue ink

Berlingo TRAINGLE FUZE RT is an automatic ballpoint pen with a 0.7 mm tip and blue ink, designed for everyday writing tasks. The pen features a triangular barrel that promotes an ergonomic grip and helps reduce hand fatigue during extended use. A retractable mechanism protects the tip when not in use, while the compact construction ensures portability and dependable ink delivery for consistent, clear lines.

Advantages

The triangular barrel provides a stable, comfortable hold that supports proper finger placement and control.
