Uni Jetstream x Karimoku 4&1 Multi Pen – 0.7 mm

Experience smooth Japanese writing and refined craftsmanship with the Uni Jetstream x Karimoku 4&1 Multi Pen. This premium multifunction pen combines four 0.7 mm Jetstream ballpoint ink colors—black, red, blue, and green—with a 0.7 mm mechanical pencil, giving you five writing tools in one compact design.

The grip is crafted from wood offcuts created during Karimoku furniture production, giving discarded material a functional new purpose. Finished with furniture-inspired techniques, the wooden grip provides a warm, comfortable feel and a distinctive natural appearance.

Known for its low-friction oil-based ink, the Jetstream multi pen delivers smooth, clean, and consistent writing for note-taking, planners, schoolwork, office documents, and everyday use. Its premium construction and presentation also make it an excellent Japanese stationery gift for students, professionals, and pen collectors.
