The uni-ball Gel IMPACT UM-153S rollerball pen with a 1.0mm line width is a premium signing instrument from Mitsubishi Pencil (Japan).

Key Features of the Uni-ball Gel IMPACT UM-153S Signing Pen
Premium Rollerball Ink, Smooth Feel, and Smudge-Resistant
The pen utilizes an advanced water-based gel ink formula engineered with Japanese technology, delivering a writing and signing feel as fluid as a fountain pen. The ink flows consistently, adheres well to paper, and dries quickly, preventing smudging or bleed-through on the back of documents to keep official records looking professional.
Bold 1.0mm Line Width for a Professional Impression
Featuring a 1.0mm tip size, the pen produces thick, prominent, and authoritative signatures. It is well-suited for executives, managers, and business owners who regularly endorse corporate contracts, legal paperwork, or commercial agreements.
Comfortable Rubber Grip Designed for Extended Use
- Ergonomic Grip Section: The holding area is covered with a soft rubber grip that ensures a non-slip hold, reducing finger pressure during repeated signing or writing.
- Modern Body Design: Sturdy construction paired with a sleek aesthetic matches high-end corporate office settings.
- Cost-Efficient with UMR-10 Refills: When the ink runs out, enterprises can easily swap in replacement cartridges under code UMR-10 (order code 037862 for blue ink), reusing the pen body to lower stationery expenses and minimize plastic waste.
Standard Color Options for Corporate Workflows
The product comes in two essential ink colors, fully aligning with administrative documentation standards in B2B environments:
- Blue: The preferred choice for signing contracts, legal documents, VAT invoices, and major agreements.
- Black: Ideal for archived records, executive meeting minutes, and corporate files.
