We have tested many metallic gel pens and Uni-Ball's Signo Gel Impact is by far our favorite choice. The ink is highly opaque, particularly dramatic on darker papers, and the metal tip is engineered to deliver a smooth flow with consistent opacity that never skips. The 1.0 mm tip is bold, but not too much so, to suit a wide variety of your writing needs.
