Diamine Cult Pens Deep Dark Inks

Cult Pens has their own exclusive Diamine ink collections including the Deep Dark collection: Deep Dark Brown, Deep Dark Red, Deep Dark Orange, Deep Dark Green, Deep Dark Blue and Deep Dark Purple. All six inks are available in both 80ml and 30ml bottles. I purchased the 30ml bottles from Cult Pens.

Swabs:

Left to right: Deep Dark Brown, Deep Dark Red, Deep Dark Orange, Deep Dark Green, Deep Dark Blue and Deep Dark Purple

Writing samples:

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

Water resistance: Low

Feathering: Low-there was a little bit of feathering in the flex nib.

Show through: Medium

Bleeding: Low-there is some bleeding in the flex nib.

Other properties: low shading, low sheen, and no shimmer. Deep Dark Blue is the only one out of the six that has medium sheen instead of low.

On Staples 24 lb copy paper there was lots of feathering in every nib size as well as bleeding, so I would not recommend these inks for cheap paper.

Comparison Swabs:

Deep Dark Brown is warmer and darker than Diamine Espresso.

Deep Dark Red is similar to Diamine Mozart from the music collection.

Deep Dark Orange is more vibrant than Sailor Ink Studio 973, but less vibrant than Diamine Blood Orange.

Deep Dark Green is a bit darker and less saturated than Monteverde Jade Noir.

Deep Dark Blue is more saturated than both Sailor Ink Studio 642 and Robert Oster Blue Night.

Deep Dark Purple is similar to Diamine Grape.

I used a Lochby Lined Blank A5 notebook (Tomoe River 68gsm). All of the inks had an average flow.

Overall, these inks are pretty standard Diamine inks-well behaved, great colors and affordable. Out of the six, Deep Dark Orange is the most unique, and my favorite from the collection. For $2.50/30ml, you can’t go wrong.
