The first Oster ink I think is unattractive
It may just be my personal taste, but having tried more than 20 of Robert Osters inks, this is the first one I find to not have a nice basic colour-scape. In dry pens it looks washed out, and in wetter pens it looks like swamp sludge. Apart from the colour, it is a good ink. Well-behaved and not prone to bleeding or feathering, but just personally, I can not get excited about this particular shade.
