Ballpoint pen Staedtler triplus ball 437 — green ink, single pen

Staedtler triplus ball 437 — green ink, single pen is a triangular, ergonomic ballpoint pen designed for everyday writing. This single pen delivers green ink with an extra-broad line suitable for note-taking, office tasks and general handwriting. The pen features consistent ink flow, a compact design and an automatic pressure equalization system that prevents leakage during flights.

Advantages

The triplus ball 437 offers particularly smooth writing performance and clear, even lines thanks to its reliably flowing ink. Its flight-safe automatic pressure equalization protects against unwanted leaks when travelling by air, and the compact, ready-to-use design fits easily into bags, pockets and pen holders.

How to use

Usage recommendations
