History for Monami

Monami appears to be a company based in Korea (http://www.monami.com/en/). They sell fountain pens among other things. A popular fountain pen is the Olika, which comes with cartridges in a colour corresponding to the pen's colour. "Olika" means "different" in Swedish. Another pen model of theirs is "Penna" meaning "pen", a third is "Rein" which in German means "pure, clear, clean".
The well-behaved inks are hard to find on the web. They come in twelve colours, in upside-down diamond shaped bottles, or in cartridges (International Standard), seven to a package.

A lot more information, articles and items for sale are available on their Korean website, than the English version. This includes a DIY ink lab set. However it seems you can only buy things as a reseller.
