Pen not writing? Free trick to fix it

Heat the tip of the pen with a lighter or match for a few seconds.
Don’t overheat: Keep the flame moving to avoid damaging the plastic.
Try writing again. Heat improves the fluidity of the ink.
Method 2: Use friction
Wrap a rubber band around the body of the pen.
Quickly rotate the pen in circles for a few seconds.
This creates friction, unlocking dried ink and allowing it to flow.
Method 3: Soak in hot water
