Key Features of Retractable Gel Pen uni-ball Signo 307
Advanced Cellulose Nanofiber Gel Ink
The Signo 307 gel pen utilizes advanced ink technology blended with Cellulose Nanofiber. This technology dynamically adjusts the ink's viscosity based on writing speed:
- Continuous lines during fast writing: Whether quickly jotting down notes during meetings or signing off on paperwork, the ink flows consistently, darkly, and without skipping.
- Reduced ink blotting: The ink adheres securely to paper surfaces, minimizing clumping or blotting at the pen tip.
Clear and Smooth 0.7mm Line Width
Featuring a durable stainless steel tip paired with a 0.7mm ball size, this pen delivers bold, clear lines. The product is well-suited for signing contracts, writing report notes, or filling out administrative forms.
Water-Resistant and Fade-Resistant Ink (Super Ink)
The proprietary Pigment ink from uni-ball offers water resistance, fade resistance over time, and chemical resistance. This feature helps protect critical documents, accounting records, and archive materials from blurring or damage caused by exposure to water or light.
Ergonomic Design with Rubber Grip
- Convenient push mechanism: Effortlessly extend or retract the pen tip with one hand, preventing cap loss.
- Soft Rubber Grip: The soft rubberized grip area provides anti-slip comfort and minimizes hand fatigue during prolonged writing sessions.
- Modern barrel: Features a refined design with a carbon-patterned texture suitable for professional workplace settings.
