Ink Review 

Supplies Used:

Smear Test (Dry Time):

  • 20+ seconds – This dried fairly quickly despite how wet it writes. The ink was dry by 30 seconds and showcased a lot of shimmer.

Drip Test (Water Resistance):

  • Low – We found this ink did not hold up to water well, though it would still be perfect for desk top journaling.


  • High – The rich dark browns come through as the Swabs from 1 to 3 and the shimmer is quite robust.

Ease of Cleaning:

  • Low – As with any shimmer ink the particulate is difficult to rinse away, we recommend our Goulet Feed Brush to help scrub down any stubborn deposits of shimmer.


  • Medium-Low – The ink its self does not have much shading but paired with the gold shimmer you will see some color variation especially when the light hits just right.


  • High – This is a pretty wet writing ink and it flows readily without causing an issue on some less fountain pen friendly papers.

 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 may seem like just a warm brown, but once it's on the page, it shines! The brown paired with the warm gold shimmer creates a dynamic writing experience. Brown is a somewhat overlooked color, especially for ink, but this is a must try.
