Graf von Faber-Castell is a teal shade with a strong grey undertone. It’s quite similar to Pelikan Edelstein Aquamarine but Graf von Faber-Castell Deep Sea Green is darker and grey-er. It’s a dry ink with a good dry time and it also shades well in the right pen. It goes from a pale grey-green to a dark green. Personally I prefer this over Pelikan Edelstein Aquamarine. Which is your favourite of the two?
