Opus 88 Koloro Demonstrator

personally i don't like this pen, but since my advisor insists i keep a copy....

I was not impressed with the mechanism, and even more worried for a plastic rod soaked in ink, as compared to the metal rod that twsbi or pilot uses. with the constant pressure and soaking in ink, that rod....has to be of some quality.....somehow.

a Vac can self refill, is about the same capacity and the twsbi vac costs much less. so, if i'm to choose, this isn't my choice.
