De Atramentis are well known for for their handmade, quality fountain pen inks. Handmade in Germany by Dr. Franz-Josef Jansen with dyes sourced from within Europe. Special inks include a range of scented inks, and De Atramentis are particularly known among fountain pen fans for their permanent Dokument inks, which are safe to use in fountain pens - though a little extra care is always best with this type of ink.
