The Signo Broad UM-153 is a super broad, super wet gel pen. It’s most notable for for being the most popular white pen, which is very commonly used by artists for watercolor painting. The UM-153 has popular gold and silver colors as well.
The Signo Broad is a lot like the UM-151 but with a larger, broader tip (1.0 mm to be exact). They are both capped gel pens with plastic bodies and rubber grips. Contained in their rather unexciting exteriors are actually great pens — they are consistent, have lots of colors, are super smooth writers, and aren’t expensive.
The Signo Broad is one of the broadest, wettest gel pens sold today. This is especially useful with the white color because it can serve as a White-Out (a correction fluid) for artists who want to make a change on their work.
These pens are very popular with artists because they use water-resistant pigment ink that can hold up to brushstroke and watercolors.
