Jetstream 4&1 Multipen - Metal Edition – Dark Green

A sleek, metalic aluminum upgrade to Japan’s most popular multipen.

The Uni Jetstream 4&1 Metal Edition takes Mitsubishi Pencil’s classic multi-function pen and gives it a sleek, industrial overhaul. Designed for anyone who prefers a sturdier, cooler feel in the hand, this edition swaps out the standard rubber grip for precision-machined aluminum with a knurled texture. The metal front section shifts the pen’s center of gravity forward, giving you a remarkably stable, well-balanced writing feel that reduces hand fatigue during long writing sessions. Inside, you get the full utility of five tools in a single body: four colors of Uni’s low-friction Jetstream oil-based ink (Black, Red, Blue, and Green in 0.5 mm) plus a built-in 0.5 mm mechanical pencil. Jetstream ink is celebrated for flowing with the smooth, vivid clarity of a gel pen while drying virtually instantly on paper, keeping pages clean and free of smears. Available in refined metallic finishes like Dark Green, Gunmetallic, and Ice Silver, it’s a premium everyday carry workhorse built for work, study, and daily planning.
