To be honest, this is not ok for office use (duh)
Color wise is nice, a very pale sky blue color with relatively short drying time (less than 10 sec) However, it is too pale to a point my boss was not very happy when I had this in my random note. This color is similar to J. Herbin Diabolo Menthe but slightly bluer.
With not-so-saturated and drier ink flow, it did not bleed through iPaper UCCU or DoubleA. No water resistant as the rest of the set, pretty much just for having the entire set to get this bottle (again…)
CP value: ??, since it’s sold out. I might not get this color if I don’t want to have the set…
