Ink Review 

Supplies Used:

Smear Test (Dry Time):

  • 25-30 seconds – This ink has quite a long dry time, but with so much going on, you may expect as much. Be careful with your hand and finger placement, and don't forget to give the page a second or two to dry before flipping it over to avoid smears.

Drip Test (Water Resistance):

  • Low –  With such high saturation, the ink will be left on the page. Don't write your checks with this one!


  • High – You'll get a rich and saturated dark blue color from the first swab. Further swabs don't add much to the saturation, so this one is loaded from the start.

Ease of Cleaning:

  • Low – Shimmer particles and highly saturated ink mean this one will be a bit harder to clean out of your feed. Make sure to not let it dry in the pen, as it will clog your feed unit. To combat this, you can use the Goulet Pens Feed Brush to clean out the shimmer after disassembly.


  • Low – There's no genuine ink shading here, but the shimmer deposits in the same fashion as shading inks, so you do get a lovely gradient and extra shine where the ink pools. It provides a lovely look with each stroke of your fountain pen.


  • High – The flow on Shimmering Seas is quite generous, which helps get the shimmer onto the page. This ink also has a surprisingly even distribution of shimmer.

 Packaging and Aesthetics:

  • The Shimmertastic series comes in a tall glass bottle with a cute gold cap and well-designed labels. Diamine has sturdy glass bottles for all their inks, which look great on a desk!

At first glance, this ink might seem dull in the bottle, but once it's on the page, it's a show stopper. The rich blue paired with the warm gold creates a dynamic writing experience.
