Diamine Ancient Copper is a very special ink. It shades in the most beautiful way and really does look like ancient copper. In that respect, Diamine picked an excellent name. If you know your way around a flex or italic nib then you’ll be able to really bring this ink to life. Even if you can’t, it is, in my opinion, an essential ink because of the joy it will bring to you and your pen.
