Mitsubishi Uni Jetstream 4&1 Multi-Function Pen 0.7mm + 0.5mm Mechanical Pencil
For those who like their writing to feel confident and unmistakably present on the page, the Mitsubishi Uni Jetstream 4&1 Multi-Function Pen with a 0.7 mm tip delivers exactly that—without sacrificing smoothness or control. This thoughtfully engineered pen brings together four ballpoint inks and a mechanical pencil in one neatly balanced body, offering five everyday functions in a single, dependable tool.
The star of the show is Uni’s ultra-low-friction Jetstream ink, designed to reduce writing resistance by up to 40% compared to traditional oil-based ballpoints. Even with the broader 0.7 mm tip, the pen glides effortlessly across the page, producing bold, confident lines that feel smooth rather than heavy. The ink’s high-density formulation—roughly twice that of standard inks—ensures writing remains dark, crisp, and legible on virtually any paper.
Quick-drying performance helps keep smudging to a minimum, making this pen especially kind to fast writers and left-handers. Internally, a spring-loaded tip and twin-ball mechanism support the low-viscosity ink while preventing leaks and backflow, ensuring consistent performance whether you’re jotting quick notes or settling in for longer writing sessions.
