uni-ball &knot pen refill

The original Jetstream refill that powers the uni-ball &knot Carabiner Pen. The SXR-80-05 refill is an oil-based ballpoint refill with Jetstream ink — smooth, quick-drying, and fade-resistant. A special spring mechanism prevents leaks, and a double ball at the tip blocks ink backflow. The result: clean, reliable writing every time.
