Pins in a pin holder do not fall even when it is held upside down. This happens so because, the opening of the pin holder is magnetic. A magnet is a substance that attracts iron and steel and certain other alloys.
Thus, if any pin is falling the magnet on the opening attracts the pin and do not let not the pins fall down.
