The uni-Ball Signo RT1 is an ultra-fine retractable gel ink rollerball pen with a 0.38mm tip. The newly designed stainless steel tip reduces frictional resistance for smooth, skip-free writing, while the improved gel ink formula delivers vivid, crisp colour from start to finish.

The semi-transparent barrel matches the red ink colour and is fitted with a rubberised grip for comfort and control during extended writing sessions. The retractable mechanism protects the tip when not in use. Supplied as a box of 10 pens.
