Diamine Inkvent Calendar 2019/Blue Edition 2020 #20 Midnight Hour

Another sheener:

Diamine has been producing highly saturated sheening inks for quite a while and so it was not too surprising that this kind of ink also found its way into the Inkvent Calendar.

This one, Midnight Hour, is one of the more well behaved, a deep blue(-black) that I really liked in the three pens it was filled into: An small OMAS Dama Grey Celluloid F, a vintage Kaweco Sport V16 (pistonfill) B and a small Montblanc 114 Mozart IM.
