If the pen "dries out" – replace the cap and leave for a few days and it will restore itself. If the tip becomes blunt, cut off the final millimetre and the tip will be just like new again. This can be done several times as the tip is telescopic and can be pushed back and forth. You can also remove the entire ink stick and rotate it 180 ° so the tip is like new again.
