Uni-ball Corporation UBC60027 Rollerball Pen 0.5mm Blue Black 12pk

Product Description

The UNI-BALL CORPORATION UBC60027 is a capped rollerball stick pen designed for professionals and detail-oriented users who require consistent, precise lines. The pen features a 0.5 mm fine tip loaded with blue black acid-free liquid ink. The ink uses uni Super Ink technology, which bonds with paper fibers to resist water exposure, fading over time, and fraudulent alteration of written text. The tip is engineered for durability, maintaining point integrity through extended use for note-taking, document signing, detailed drawings, and list-making. Each unit ships as a dozen of 12 pens.

This pen is suited for office, administrative, legal, and professional environments where ink permanence and line consistency matter. The acid-free ink formulation makes it appropriate for archival document work, contracts, and records that require long-term legibility. The capped design protects the tip during storage and transport, reducing the risk of drying or damage. The fine 0.5 mm tip produces clean, controlled lines on standard paper stock, making it a reliable daily-use writing instrument.
