UNI UMR-85 Gel Refill – Flawless Writing Durability

Product: UNI UMR-85 Gel Refill (for UMN-152, UMN-105, UMN-207)
Color: Blue

Anyone who values handwriting clarity and document security knows that a high-quality gel refill is a necessity, not a luxury. The UNI UMR-85 model has become an industry standard due to its unique pigment ink, combining smooth gliding with maximum resistance to external factors.

1. Unique "Super Ink" Technology

The main advantage of this refill is the Uni-ball Super Ink technology. This special pigment ink possesses properties essential for signing important documents:

• Resistance: The ink is fully waterproof, resistant to direct sunlight (fade-resistant), and even chemical tampering, ensuring your records remain legible for decades.
• Fast Drying: This is one of the fastest-drying gel refills on the market, making it an ideal choice for left-handed writers as it prevents smudging on hands and paper.

2. Precise Line and Writing Feel

Despite the 0.5 mm tip size, this gel pen refill creates an elegant 0.3 mm line. This allows for fine yet clear writing, perfect for filling out forms or writing in small planner grids.

• Consistency: The stainless steel tip with a tungsten carbide ball ensures smooth ink flow without skips until the very last drop.
• Control: The gel consistency provides easy gliding, significantly reducing hand fatigue compared to standard ballpoint pens.

3. Universal Compatibility

Although officially designed for the popular UNI UMN-207 models, it features a universal 11.2 cm length. This means it fits many other retractable gel pens using a similar mechanism. It’s an economical way to breathe new life into an old pen while being eco-friendly by reducing plastic waste.
