Don’t know how it happened but I went to remove my stylus and only 1/2 came out! I broke in the middle not at the seam between the body and the head. Thinking about super glue and a strong piece of wire unless someone has a better idea.
You could try screwing a long screw into the broken stylus just enough to grab hold and pull out
I took a drill bit and a dab of super glue. Make sure its completely dried b4 putting the pen back. Good luck.
