Broken-up expression in Wacom Bamboo?

I really need some help right now.

My drawing pen on my laptop (a Wacom Bamboo pen without a separate tablet) broke off when he fell down.

I've got more faces lying around here at home. Unfortunately, they do not fit in, because the lower half of the old face is still inside. Unfortunately, I can't get out because the opening is very narrow.

Do you have any tips how to get them out of there? I just do not want to buy a new pen because of my face

Can you show a picture? From Bamboo gabs several generations with different pencil models…

I add pictures right to my question.
