I have had a Montblanc Meisterstuck sitting in my drawer for years. I cannot remember whether it was a ballpoint or rollerball (I had both at one time), and the refill was missing. So, I had it in my motorcycle jacket to bring to work and snap some good pics. Well, I sling my jacket on not thinking, and the pen lands on the ground. It busted the end cap (where you post the cap). Precious resin 0, concrete garage floor 1.
