Most of the time I just review whatever inks are next on my list, but sometimes I like to do a theme for the week. This week’s theme is blue-black inks. Pilot Iroshizuku Shin-kai, aka “Deep Sea” is an ink I use often, and I was surprised when I realized I’ve never actually reviewed it. A pen friend was very kind and gave me my bottle, but you can find this ink for sale at Pen Chalet.
Shin-kai is a medium blue-black.
In large swabs on Tomoe River paper the ink looks more blue with some red sheen.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 15 seconds
Water resistance: Medium-some of the ink washed away but you might still be able to read what was written.
Feathering: Low-there was a little bit of feathering in the flex nib on Leuchtturm paper.
Show through: Medium
On Staples 24 lb copy paper the ink feathered in all nib sizes and had a little bit of bleeding.
I used a Lamy AL-star Pacific Blue with a fine nib on Tomoe River paper. The ink had a lovely wet flow.
Overall, I love this ink, and use it often. I love the color, shading, wet flow, and quick dry time. Since I only have the small 15 ml bottle, I’ll buy a full-size bottle when it’s gone.
