Experience the ultimate in writing efficiency with the Uni Jetstream 3-Colour Ballpoint Pen, a thoughtfully designed multi-pen that prioritises your most-used ink. This model features a revolutionary "top-knock" mechanism specifically for black ink, allowing you to deploy it intuitively just like a single-colour pen, while the red and blue inks are easily accessible via side-slide buttons.
Powered by Uni’s world-renowned Jetstream oil-based ink, this pen delivers an incredibly smooth, low-friction writing experience that dries almost instantly—making it a top choice for left-handed writers and fast note-takers. To ensure you never run out during important tasks, the black ink is equipped with a "Long-Lasting Refill" (SXR-ML), containing 70% more ink than standard refills.
Available in a curated selection of stylish barrel colours and two tip sizes to suit your writing style:
