The next Ban Mi fluorescent ink is Green. It is very bright green, but it is barely legible.
The packaging on these inks was not clear if they are safe for fountain pens, but I have used them in Jinhao 82 pens and had no trouble using the ink or cleaning it after. I have not tested its water-resistance, but it does look similar to pigment inks in other ways, so take care with their use.
Scans
My scanner, like many others, does not do well with fluorescent colors, so these are mostly for consistency and to show how badly it handles them.
The scans show pale green, but it’s too faint and not quite the right tint.
Photos
In photos, it looks better, at least it’s consistent with how it looks to the eye. It’s extremely difficult to read!
It looks good under full UV, though. Especially on MD.
Microscope
Under magnification it’s very shiny. I’ve seen that before with pigment inks where it has a gloss over everything.
It gets darker around the edges, but there isn’t any sheen other than the gloss that covers everything.
Microscope UV
With UV under magnification it’s about the same as the photos. MD has the best contrast by far.
Chromatography
As with the swatches, the scan of the chromatography strip doesn’t show much.
A photo of the strip shows mostly a very faint light green line and a little bit spread from there. Also similar to behaviors I’ve seen from pigment inks.
Under UV, the green area glows very brightly, and there is a faint blue halo way beyond that area.
Verdict
It’s very difficult to read in visible light, but like the others, it would probably work OK as a highlighter/accent ink. Under UV, it’s great on Iroful and MD.
I mentioned earlier I haven’t had any trouble with it in a fountain pen, but treat it like a pigment ink to be safe.
