I don’t hesitate to use pigmented inks in most pens, but given the added care required, I will be particular to choose one that is easily cleanable, and that I will be using daily. If it isn’t in my regular writing rotation, it gets cleaned.
I’m impressed with my first Octopus Fluids experience so far. I’m a pigmented ink fan due to the colors available and permanence of the formula, and this Write & Draw Petrol Buffalo is as good as any as I have used. The price is right, too, at just over $17 for a 50 ml bottle. I have some of their standard inks on hand also, and so far so good with those as well. If their formulas or colors are something that ticks your boxes, I wouldn’t hesitate to recommend them.
