Diamine Inkvent Calendar 2019/Blue Edition 2020 #01 Blue Peppermint
Diamine Inkvent Calendar 2019/Blue Edition 2020 ink #01 Blue Peppermint is a turquoise shimmering ink.
As with any Diamine Shimmering (Shimmertastic?) ink I have tried so far there are no problems to fear if you only be aware of the fact that shimmer inks need wetter pens to perform best.
I had this ink in a Sailor 1911s (Profit Standard) with a wet music nib in December; in April I filled it into a Sailor Pro Gear Slim Mini(fied — a nice engineery guy was kind enough to shorten the pen to mini size) Shikiori Yukitsubaki with a zoom nib.
