Uni-ball Micro Deluxe Rollerball Pen, 0.5 mm, Waterproof Pigment, Smooth Uni-Flow, Metal Clip, Ideal for Everyday Writing - Blue

Main specs: 0.5 mm fine point for crisp lines; pigment-based, water-resistant ink; quick-drying to reduce smudging; smooth flow with a flow regulator; metal clip for secure attachment to notebooks or planners.

Pigment ink sits on the surface rather than soaking into the paper like dye inks. This provides better archival quality, holds up to handling, and resists fading from light moisture better than many dye inks.

Cap on when not in use to prevent drying. When writing, hold the pen at a comfortable angle and apply steady pressure for a smooth line. If the ink seems a bit dry, give the nib a gentle write on scratch paper to prime it again.

Ideal for notebooks, planners, forms, and everyday writing on standard paper. It’s not optimized for glossy surfaces, but it performs well on typical office and school papers.

Yes, it uses standard 0.5 mm Uni-ball rollerball refills. Look for blue 0.5 mm rollerball refills compatible with UB155/UB150-series pens to extend its life.

Compared with the Uni-ball Vision Elite 0.5 mm Rollerball, Micro Deluxe offers a slimmer profile and faster-drying pigment ink for tidier note-taking. Vision Elite may have a slightly different nib feel and cap design.

Perfect for daily journaling, taking notes in meetings or classes, signing documents, and making checklists—anywhere you want precise, clean blue lines with quick-drying ink.

The pen uses non-toxic, standard office-safe pigment ink designed for general use. It’s suitable for classrooms, offices, and homes, with no special handling required beyond normal care.

For its fine 0.5 mm precision, pigment-based ink, and sturdy metal clip, it offers solid value in the mid-range segment. Its combination of durability and archival-quality ink makes it a reliable everyday writer.

Look for official Uni-ball branding, the UB155-01BE model designation on the body or packaging, and verify the product URL corresponds to Fepy’s product listing. If in doubt, compare ink color, tip size (0.5 mm), and clip design with the official Uni-ball specs.
