Initially, I had to fight to fill my Conklin Duragraph Stub pen. Eventually, I used a blunt syringe to fill the pen. The bottle is very short and I have yet to get the insert out of the bottle so that I can fill pens easily.
It would be easier if the bottle was taller.
But the bottle opening was good and I am certain that, when the insert gets removed, I will not have the problem.
The smell wasn't bad.
My first thought of the colour was, where is the sheen that people tell me about? It was not showing. I did not like the colour initially.
But the ink goes well on basic photocopy paper and frankly, the colour is growing on me. It writes smoothly and very little feathering. I prefer this ink to the mandated Red Ink and very few people have noticed.
The colour is more burgundy, with shading that approaches (occasionally) green, via red-brown.
This ink is a keeper, but hate the bottle.
