Bold and Tamper-Proof Writing The Uni-ball UM-153 stands out for its exceptionally rich, opaque line. It uses Uni-ball Super Ink, a high-quality pigment ink that actually becomes trapped in the paper fibers. This makes your writing tamper-proof, waterproof, and fade-resistant—essential for signing important legal documents or checks in Amman. The 1.0mm broad tip provides a luxurious, gliding sensation that makes writing feel effortless, even on textured paper.

Ergonomic Design for a Secure Grip This pen is designed with a wide-diameter barrel, which is often preferred by those who find slim pens tiring to hold. The integrated rubber grip is ergonomically shaped to provide maximum control and comfort during long writing sessions. Because it is a liquid-style gel ink, the UM-153 produces a consistent, bold mark from the first stroke to the last, and the transparent section of the barrel lets you monitor the ink level at all times.

Archival Quality for Professionals In Jordan, the Uni-ball Signo Broad is highly respected for its archival quality. It is widely used by calligraphers, architects, and business executives who need their work to stand the test of time. The pen is refillable (using UMR-10 refills), making it a sustainable choice for your home or office. Whether you are addressing an invitation or finalizing a contract, the UM-153 delivers the bold, permanent, and professional finish you demand.
