Hi guys, I just got my first TWSBI yesterday, a classic mini with a 1.5 mm stub nib. Inked it up with Shaeffer Skrip blue black. After writing a few pages with it with no issues, I notice the ink color lightening in saturation. This goes on until I force a bit of ink to the feed. The pen lays down a dark line again, but after a few pages, lays down a diluted looking ink color line! Frustrating, indeed. Add to that the occasional skipping I get, but as of now, I'm even willing to attribute that to the fact that I'm still getting used to the stub nib (my first). I've read many good reviews about this pen, so I'm still hopeful. I would appreciate to hear your input on what I can do to improve its performance. Can it still be improved? Has anyone ever experienced getting a brand new, but defective TWSBI pen? Thanks in advance!
