Blue-black fountain pen ink from DeAtramentis, handmade in Germany.

Sigmund Freud was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst.

This ink is made by hand in small batches, therefore there could be some color variation between bottles of ink.
