Mitsubishi Uni Ball Signo RT1 Gel Pen – 0.5mm
Description
The Mitsubishi Uni Ball Signo RT1 Gel Pen – 0.5mm is proof that a simple pen can still contain a fair bit of clever engineering.
At its heart is an innovative edgeless tip design. The rounded, smooth tip reduces friction against the page, allowing the pen to glide with remarkable ease. The result is a writing experience that feels fluid, controlled and satisfyingly smooth — particularly welcome when producing fine lines.
Complementing the tip is Uni’s improved Signo gel ink formula. The colours appear vibrant and consistent while maintaining the precision expected from a 0.5mm point. The ink is also water-resistant, fade-resistant and archival-quality, making it suitable for documents that need to last.
The body follows a similarly thoughtful philosophy. A rubber grip blends almost seamlessly into the barrel, creating a one-motion design where the transition between grip and shaft is barely noticeable. It feels natural in the hand and remains comfortable through longer writing sessions.
Elegant, practical and quietly refined, the Signo RT1 is an excellent everyday pen for notes, journalling, sketches or detailed writing.
