Pen Off A Calculator?

Question

My friend borrowed my calculator. She forgot to put it back in it's case so it was in her backpack in her pencil/pen case. An open pen got scribbles all over it. I'm not mad at her and she already apologized. How can I get the pen off without damaging my calculator?
