The Uniball Signo RT1 provides an exceptionally smooth writing experience for a 0.38 mm pen. Its edgeless and rounded tip design minimizes friction with the page. The pigment-based gel ink produces a smooth, clear, and sharp line, and it is waterproof, fade-resistant, feather-resistant, fraud-resistant, and archival-quality.
The design of the Signo RT1's body further enhances its smoothness. The comfortable rubberized grip integrates stylishly with the barrel, and the pocket clip attaches seamlessly to the push clip. The semi-transparent colored barrel allows you to see the ink level, so you know when it's running low.
