Supplies Used:

Smear Test (Dry Time):

  • Medium – This ink took about 20 seconds to dry, which is great.This would be very convenient when writing letters or using your journal.

Drip Test (Water Resistance):

  • Low – If you're looking for water resistance, this isn't the turquoise ink for you. You can get wide range of color by adding water to the ink, however. But know that if you spill water on your notebook inked up with Marine, you'll be out of luck.


  • Low – This is not a highly saturated ink; you can see the difference in the swab test. You'll see below that Marine looks different in a range of different nibs and sizes. It can range from a deep turquoise, to a lighter teal depending on what pen you ink up.

Ease of Cleaning:

  • Easy -No issues here with cleaning. This ink is easy to use and easy to clean!


  • High – Diamine Marine is included in Brian's top inks list, and for good reason. The shading is beautiful!


  • Medium– This ink has great flow, and a quick dry time. That's a win-win in my book.

Packaging and Aesthetics:

  • 30ml plastic, 80ml glass bottles and cartridges are available. 
  • The bottles are easy to fill from.

Drawing with Diamine Marine ink

While it's not your standard blue or black ink, it's professional enough to be used at school, or while jotting down notes in most meetings. It offers incredible shading, it's easy to use in a variety of pens, and it flows nicely. The only drawback is that it won't offer you any water resistance. But as long as you know that before using it, don't hesitate to ink up with Diamine Marine!
