rOtring Ballpoint Pen Refills (Small)

Ballpoint pen refill for 3-in-1, 4-in-1, and Trio Pens. Lead diameter: F (Fine) 0.5mm. Founded in 1928 in Germany, during a time when the Bauhaus design school's influence was strongly reflected in art and architecture, rOtring has produced numerous minimalist yet high-performance products based on the belief that "precise lines are beautiful" and the Bauhaus philosophy of "art in industry." Even as times change, the process of "refining ideas"—the process of giving shape to ideas—remains unchanged for creators and engineers. And when inspiration strikes, they visualize their ideas and expand their imagination infinitely. rOtring has been there for this process, supporting the creativity of professionals.
