Uni-Ball Signo Gel Pen -- Angelic Color AC White (UM120AC.1)

The Uni-Ball Signo Angelic Color in white is a gel marker with a fine ballpoint, and a good companion to the Uni Signo broad point that I also use. It has a lovely opaque ink. I've used it on acrylic paint and acrylic ink after these have completely dried and the white colour is really noticeable and opaque when used on dark colours; not so much on light colours. The ink flows beautifully and creates polished clean delicate lines or accents. It is not archival, though, so you have to be careful not to smudge it when moving your hand around. This being the case, a fixative is needed if used on artwork. For the rest, it's a lovely marker at a great price.
