Robert Oster Crystal Marine was sent in by a reader, and as soon as I swatched it, it reminded me of Robert Oster Marine (which I love), and I’m pretty sure Crystal Marine is Marine with blue shimmer added.
Crystal Marine is a dark teal with blue shimmer.
In large swabs you can see the dark blue shimmer and some of the dark pink sheen.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 20 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was a bit of bleeding and feathering in the flex nib and a bit in the other nib sizes as well.
I used a Pelikan M805 Ocean Swirl with a broad nib on Tomoe River paper. The ink had an average flow.
Overall, I love the color, and it’s nice to see some blue shimmer instead of the standard silver/gold. The only other ink I have with blue shimmer is Robert Oster Black and Blue.
