Uni Jetstream x Karimoku 4&1 4 Color Ballpoint Multi Pen 0.5mm + Mechanical Pencil 0.5mm

JETSTREAM × Karimoku 4&1 Multifunction Pen 0.5mm

Where furniture craftsmanship meets everyday writing. This special JETSTREAM 4&1 collaborates with karimoku, the renowned Japanese furniture maker, using upcycled walnut wood offcuts from their furniture production as the pen's grip — each one finished with the same urethane coating used on karimoku furniture for a soft, premium touch.

Because it's real wood, every grip carries its own natural grain, tone, and character — some even showing the subtle seams where offcuts were joined together. A "karimoku" logo is engraved on the side, marking this exclusive collaboration.

The deep, muted colorway draws inspiration from karimoku's furniture lineup, paired with a soft-feel coating that only grows more comfortable with use — designed to be cherished for years, just like a well-loved piece of furniture.

Inside, you get the smooth, addictive JETSTREAM writing experience across 4 ink colors plus a 0.5mm mechanical pencil — perfect for organizing notes, planners, and documents in daily life.

A pen with a story, crafted to last.
