The uni-ball SIGNO UM-153 gel roller in silver offers a pleasant and precise writing experience with water-resistant and archival-quality pigment ink. It is particularly suitable for writing on dark surfaces, as the ink is highly visible. With a line width of 0.6 mm, the metal tip ensures clear lines. The ergonomic, rubberized grip area guarantees comfort while writing. The pen features the Free Ink System, which prevents the refill from drying out when left unused for extended periods. The gel roller is equipped with a plastic clip and is available in three archival-quality colors as well as an additional eight metallic colors. The barrel is gray/red, and the refill is replaceable.
