The Finnish flag with a place for four 2 x 3 MM magnets on the back. To take your Finland pride to the next level I added SISU. 

"Sisu is extraordinary determination in the face of extreme adversity, and courage that is presented typically in situations where success is unlikely. It expresses itself in taking action against the odds, and displaying courage and resoluteness in the face of adversity; in other words, deciding on a course of action, and then adhering to it even if repeated failures ensue."
