Our profound Rollerball Pens have been a symbol of American design and ingenuity. These pen sets are designed and produced with distinctive elements, including a click-off cap, polished, chrome-plated fittings, and a transparent blue lacquer finish. The Rollerball Pens are committed to providing Longevity, faultless service, and high durability. These are perfect for writing smudge-proof neatly, and optimally working. Because of their special gel ink flow like a fountain pen. In addition to this, they may be easily turned into a ballpoint pen or a creamy porous felt-tip pen by simply changing the refill to the desired tip type.
