This is a lot brighter green ink than the L Frank Baum I just reviewed. Or most other inks for that matter. There's not a lot of inks that fill that Sci-Fi green like this one does. You know the color. The alien ooze, incredible hulk, radiation monster color. This is it. To be honest, for day to day use, this one is probably a little...outside your normal color range. It is not too light to be seen like some light colored greens, and doesn't suffer from visibility issues. (definitely not) It held up better to water than the Baum, and the lines were still legible. Flow was wet, as seems to be the case for most Organics Studios inks. Basically this is your all purpose nuclear bomb, godzilla, radioactive spider bite, big green monster, sci fi serial color of ink.
