I hate this blue. Initially it was deep dark blue but after 1 week or so, it became like this. It’s worse than Parker Washable Blue 😦
Technical facts, standard drying time, wet ink flow, pretty saturated WHEN writing down, no water resistant, and didn’t bleed through iPaper UCCU or DoubleA. But other than those, I don’t know what else to say. Truly a disappointed color.
CP value: 50/100, well, it’s cheap enough when you buy a 1L bottle but no no for the color.
