It is difficult to purchase Graf von Faber Castell inks in NZ and I was impressed with the selection of colours. I bought the carbon black ink, which is a very dark black ink, meaning no green or blue undertones when mixed with water. It is not waterproof though, so it will run if one uses watercolour with it, but I like the effects. I put my order in after lunch, and it was delivered the next day in the South Island! Great service thank you.
