Jetstream RT Rollerball pen writes smooth like a gel, yet dries quickly like a ballpoint. Pen contains Uni Super Ink, a specially-formulated ink that becomes trapped in paper, helping prevent criminal check washing and other document alteration. Archival-quality, acid-free ink is ideal for documenting and record-keeping. Ink is also fade-resistant and water-resistant. Rollerball pen features retractable tip, embossed grip and stainless steel accents.
