Method 3: Soak in hot water. Fill a bowl with hot water, around 40-50°C. Soak the tip of the pen for about 5 minutes. Once you remove it, dry with a napkin, and then try writing again. This method softens dried ink.
Method 4: Lubricate with oil. Place a drop of light oil on the tip of the pen, allowing it to sit for 1-2 minutes. Make sure to wipe off any excess oil before you start using the pen again.
Finally, Method 5: Use a napkin. Draw lines on a napkin several times with the tip of the pen. The friction removes residue or dried ink, improving the writing performance of your pen.
With these methods, your pen should be back to working order. Try them out before discarding a pen that might still have some life in it.
