A friend brought me a pen to try and fix. The twist mechanism is broken. I took it apart and went to replace it with a 7mm mechanism but the tube opening is just larger than the typical mechanisms I have? The mechanism measures just over 7mm itself. The mechanism has a white plastic bottom that is wider? Sorry I can't post a picture of it. Does this sound familiar to anyone? Any help on the size and where I might get a new one? Thanks.
