I’ve never understood the fuss about the TWSBI. To me it’s just another Far Eastern pen, by no means the best of them. I’m told that it has a section to itself on Fountain Pen Network, but there are few things that surprise me about FPN. There are a great many reports about various TWSBIs developing cracks and even falling apart altogether. Probably better off with a Wing Sung, Pen BBS or Moonman, all of which seem to be more robust.
I had one briefly. It was supposed to be flexible but wasn’t. Perhaps that’s unjust. After all, you could flex a cold chisel if you can apply enough force. I sold it on, probably just in time before it collapsed into a pile of its component parts.
Perhaps you’re seething with rage by this time at the dreadful calumny I am inflicting on your favourite pen. You believe I am entirely wrong. Okay, convince me!
