HMM Plummet Ballpoint has a low center of mass, and the design is inspired by fishing float, enabling agile maneuver of the ballpoint pen for steady strokes. Made of aluminum alloy, the pen is less than 20g in weight, creating a lissome sensation. The pen features twist mechanism with smooth and sturdy damping structure, and replaceable German-made refill.
The design lowers the center of mass to expand the area of grip for enhanced comfort and stability of writing.
