Uni-Ball UM-153 Signo Broad 1.0mm Pen - Red 12-pack GR-UM153-RED

Uni-Ball UM-153 Signo Broad 1.0mm Pen - Red 12-pack GR-UM153-RED

The Uni-Ball Signo Broad UM-153 is a capped gel roller pen designed for bold, clearly defined writing on paper. Its 1.0 mm tungsten-carbide ball produces an approximate 0.6 mm writing line, making it particularly useful for marking, annotations, corrections and colour-coded notes. This pack contains 12 red pens for convenient use in offices, classrooms and shared workspaces.

Bold Red Gel Writing

The UM-153 combines a stainless-steel tip with a 1.0 mm tungsten-carbide ball to produce a prominent red writing line. Its pigment-based gel ink helps corrections, comments, headings and important information remain clearly distinguishable from standard black or blue text.

SUPER INK Protection

Uni-ball SUPER INK is formulated to resist water and solvents while retaining its colour intensity over time. This makes the UM-153 a practical option for annotations and records where clear, lasting red writing is required.

Consistent Ink Control

Uni-ball’s twin-ball system helps regulate the flow of gel ink through the tip for consistent everyday writing. It works with the broad rollerball point to support smooth, controlled lines across paper.

Comfort for Everyday Use

A soft rubber grip creates a comfortable holding area and helps improve control during longer writing or marking sessions. The capped design protects the tip between uses, while the integrated pocket clip makes the pen convenient to store or carry.
