Uni-Flow is a controlled ink-feed mechanism that steadies the ink supply from the cartridge to the nib. It minimizes ink gaps and skips, helping you achieve a uniform line from the first stroke to the last.

The pigment-based ink is designed to resist water and minor moisture, so signatures and important notes on forms stay legible after exposure to light moisture. It dries quickly to reduce smearing, making it suitable for everyday office use.

Key specs: 0.7 mm fine tip for precise lines, red ink color, pigment-based ink with quick-drying properties, water resistance, and a rounded barrel designed for comfortable, steady handwriting.

Ideal for signatures, completing forms, daily note-taking, markup and edits, and any writing where visible emphasis and clean lines are important.

Cap the pen when not in use and store it in a cool, dry place. Use on smooth, high-quality paper to prevent feathering. The rounded barrel is designed for comfortable, extended writing sessions.

If this model uses replaceable cartridges, look for compatible UB177 pigment ink cartridges designed for the same 0.7 mm nib. When refilling, insert the new cartridge with the nib aligned to the paper and test on scrap paper first.

Use the pen for its intended writing purposes only. Keep ink away from eyes and avoid ingestion. Follow standard safety guidelines for writing instruments and supervise children to prevent misuse.

In addition to red, you can often find other color variants of the same model (for example black or blue) on Fepy. Compare line width, tip size, and ink type to choose the one that best fits your writing style.

Compared to other Uni-ball rollerballs on Fepy, this model emphasizes a fine 0.7 mm tip, quick-drying pigment ink, and a comfortable rounded grip for everyday business writing. If you prefer silkier lines or different ink types, you can explore other Uni-ball rollerball or gel options on the site for a different feel.

The pigment ink with quick-drying properties supports legibility and reduced smearing, which is advantageous for professional documents. If archival quality is critical, test on your paper type and consider whether your documents will be exposed to moisture or humidity.
