Broad 1.0mm gel ink for bold, vivid black writing

The Uni-Ball Gel Impact UM-153S in black delivers smooth Signo gel ink through a broad 1.0mm tip, producing a rich, vivid black line for expressive writing, bold headings, and any situation where a broader gel ink stroke is preferred.

The Gel Impact is the broad-tip variant in the Signo family, using the same smooth gel ink formula as the UM-120 but through a wider 1.0mm tip for a more impactful, generous line. Black at 1.0mm is a strong, confident choice for headings, signing, and any writing where presence and clarity on the page matter. Capped design. Supplied in a box of 12.

  • Broad 1.0mm tip for a rich, impactful black gel ink line
  • Smooth Signo gel ink - vivid, fast-drying, consistent
  • Greater line width than the fine 0.7mm Signo for bolder writing
  • Capped design protects the tip between uses
  • Available in black, blue, and red
  • Box of 12
  • Bold headings, titles, and expressive note-taking with broad gel ink
  • Signing documents where a broad, impactful signature line is desired
  • Writing on large format paper and labels
  • Art and design work requiring a wider gel ink stroke
  • General professional writing where a broad tip is preferred

Shipping is kept simple with flat rates for selected areas and free shipping where applicable. Large, bulky, rural or out-of-area orders may require additional freight, and our team will contact you if this applies. For a more specific estimate, simply add this product to a quote.
