In the last few years Diamine has released a few series of shimmering inks. Fun inks that come in some intriguing colors. After cocoa and night sky, I decided to try moon dust. It is one of the strangest inks I have ever used. It looks like pencil writing but with more bling. As usual the shimmer is high but difficult to catch on a scanner. The ink can be used in an office setting (note taking) but is best reserved for short fun notes and greeting cards.
The ink is well behaved. No feathering, beautiful shading, negligible show-through, wet but not too wet, well lubricated and normal drying times. Shimmer is clearly visible (shake the bottle before filling your pen!), even in medium nibs. The ink can even take some water. Dropping some water on the grid and carefully removing it after 20 seconds resulted in hardly any damage.
Apart from the shimmer, which gives it a "pencil look", Moondust is normal gray ink. The difference with Graf von Faber Castell's Stone Grey or Iroshizuku's Kiri-same is not that big. Iroshizuku's Fuyu-Syogun is noticeably lighter and more blue.
All in all it's a well-behaved, fun ink with a very limited use.
