Ink Review #252: KWZ Iron Gall Gummiberry


We are kicking off KWZ week (where we do seven days of KWZ ink reviews) with a review of KWZ Iron Gall Gummiberry. Thanks to for sending a sample over for review.


The color:

Iron Gall Gummiberry is a dark, saturated purple.


When pooled, this ink turns a dark purple, almost black.


Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 55 seconds

Water resistance: Medium-some of the ink washed away but the writing was still readable.

Feathering: None

Show through: Medium

Bleeding: Low-there was some bleeding in the flex nib on Tomoe River paper.

Other properties: Low shading, no sheen, and no shimmer

On 20 pound copy paper the ink behaved well, no issues that I noticed.

Ink swabs for comparison, left to right (top to bottom for mobile RSS): KWZ (non-IG) Gummiberry, KWZ Iron Gall Gummiberry, and KWZ Brown Pink. Click here to see the KWZ inks together.

Birmingham Pens Lilac Wind, Robert Oster Dark Chocolate, and Birmingham Pens Eggplant Parmesan. Click here to see the purple inks together.


Longer writing: 

I used a broad Pelikan M805 Ocean Swirl on Tomoe River paper. The ink had a lovely wet flow.


Overall, I like the flow of this ink, and it's a great color. Give it a try, you might love it.
