Monteverde USA proudly introduces the Engage One-Touch Liquid Ink Rollerball Demo with a fine-point tip, featuring the world's first retractable liquid ink rollerball demonstrator. Made from hand-assembled clear European resin, the pen's transparent body offers a clear view of the inner workings and ink levels, enhanced by glossy black accents. This innovative pen combines the smooth ink flow of a fountain pen with the convenience of a fine-point rollerball, all in a capless, retractable design that resists ink drying. Fill the Engage Demo using the glossy black threaded converter or load it with standard international G3 ink cartridges for versatility. Packaged in a premium green Monteverde USA gift box, this pen makes an exceptional gift for professionals and collectors.
