Key Advantages of uni-ball eye Liquid Ink Pen
Water-Resistant and Fade-Proof Super Ink Technology
The uni-ball eye liquid ink pen incorporates proprietary Super Ink technology from Mitsubishi Pencil. The ink particles form a strong bond with paper fibers, making written notes highly resistant to water, light, and temperature exposure. This feature helps protect archived records, commercial contracts, and technical reports from smudging or fading over time.

Equipped with the advanced Uni-Flow System, this pen maintains a steady, continuous ink flow from the first stroke down to the last drop. Users experience smooth writing without line breakage or ink pooling, ensuring neat and professional document pages.
Convenient Ink Level Window
The pen barrel features a clear view window that enables staff to check the remaining ink level easily. This helps procurement teams stay proactive in inventory management and supply replenishment.
