Flow problem

Third comment from me on Jinhao pen. There, I'll be more assertive: I strongly advises against. The fine pen, very fine, no longer writes after a moment, the ink is solidified around. I have a Pilot Capless fine pen that does not have this problem. My hypothesis is that particularly in the case of feathers F or EF, the flow has to be very careful; gold, making these pens - contrary to what is said on online video sites "experts" Dutch or US - clearly inadequate. It is certainly my experience and my punishment for having believed in Santa Claus. So it goes on the big pen wholesale Jinhao 159, but there, literally, it no longer passes, more juice, nothing. Or he must do his toilet each time; up to you.
