Blue Moon is a gorgeous medium blue with lots of silver shimmer.
In large swabs there is lots of shimmer and some beautiful pink sheen.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 40 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was some feathering and bleeding, so it's not one I would use on super cheap paper.
Overall, it's a great color and well behaved. I love Blue Water Ice, and Blue Moon feels like the shimmer version.
