Nemosine pens first started to make an appearance around 2015/16 with the inks first appearing in 2017.  The pens are assembled in the US but are made of components from around the word e.g. German nibs.  The inks are made in Slovenia, there are 10 colours available and are all named after something astronomical.  I bought my inks from Birmingham pens where they cost $USD7.99 for 35ml (22.8c / ml) making them very reasonably priced even with conversion rates and postage to NZ.  I haven’t found the inks for sale anywhere in Australasia and as per my comments in a previous post customer service etc from Birmingham pens was excellent.
