After having been unused for a while, my TWSBI 580 and whatever the model before that was... are having the same problem. The clear plastic piece between the nib and main body seems to have expanded slightly so that it is not securely held on. I can remove those pieces now with almost no pressure from my hand. Am I right in thinking that these pieces should be tightly secured to the main body of the pen?
Has anyone else had this problem? Are the pens trash at this point?
