Both bottles have been bought in Europe, and for sure none is washable blue (one is black, the other is blue black). But the box doesn't say they're washable.
Though most people seem to be concerned with writing staying on the paper forever, the reason why I'm asking this is what Olya has said, to know whether I'll be able to remove stains from clothes easily. I don't think I'm going to write anything that will be of interest in fifty years' time.
I'm quickly developing a clumsiness complex. I'm prone to stain everything around me, but now that I've started using a syringe to fill and empty cartridges, the problem is reaching epic proportions. And I am thinking of getting rid of all ink bottles that may leave my clothes (or the floor tiles, or the wooden table, or anything) stained forever, and replacing them with safer ones.
I started with these two, because I know both varieties exist, and replacing the wrong one with the right one would be easy. But if you can tell me which of these I should be extra careful with, I'd appreciate it, too:
Waterman Absolute Brown
Waterman Harmonious Green
Waterman Audacious Red
Waterman Serenity Blue
Diamine Autumn Oak
Diamine Eau de Nil
Diamine Golden Sands
Montblanc Oyster Grey
Montblanc Beatles Psychedelic Purple
Graf von Faber-Castell Viper Green
J. Herbin 1670 Emerald of Chivor
Pelikan M205 Duo Highlighter ink
Pelikan 4001 Blue Black
Pilot Iroshizuku Ku-Jaku (sample)
Do you think any of these will leave indelible marks in my clothes, or anywhere else? The floor below my chair has had a Waterman red stain for over a year now, and I'm sure it'll survive me.
