Not sure. I just use the sketch paper in those black sketchbooks …. if pen stops working I find another one. I test it 1st on another piece of paper to make sure the ink is flowing smoothly
If I test it and write it works perfect but not if I try to draw. I always have to scratch or write at a different piece of paper to make the ink run again...
I used old pens and new ones but the ink always gives up on me. Can it be the paper or the cold?

Yes. I need to do that also … I keep another pad to scribble in circles to keep the ink flowing
