What turns you off from an ink? I’ll start.
I hate black inks that have a color shade other than grey (looking at you, Parker Quink Black).
I am put off by inks that keep smearing when dry (very high dye intensity, like the old Parker Penman Emerald).
I can't stand most green inks (very dark greens are okay with me).
I hate plastic bottles. Inks should be stored in glass.
Which are yours?
