De Atramentis fountain pen inks are exclusively handmade in Germany by Dr. Franz-Josef Jansen, and come in a 45ml glass bottle. This turquoise ink is part of the Document series and is permanent and waterproof. All of the inks in the Document series can be mixed together to create a unique waterproof color. Great for sketching with fountain pens!
Note: Occasionally the label is marked Document Ink Cyan -- this is the same color. The two names are used interchangeably from batch to batch.
Please note: The bottle is now properly labeled as 45ml volume; our pictures may still show the old 35ml label.
