My twist pen was working just fine until I put it up to do something and came back to start again. Now when I twist, it has no stop and the point won't come out. There is no turning friction when I twist the pen.
I'm unaware of what brand it is and there is no visible problem with it. I can take off the very top, which holds the clip, and that's all. It won't pull apart, and it isn't obvious how to access the inside, or the refill for replacement.
