Has your ballpoint pen stopped writing even though there's plenty of ink left? The issue is dried ink clogging the tip—a common problem I've fixed countless times in offices and homes.
To get it flowing again, gently warm the ink cartridge. This liquifies the dried ink without wasting a drop.
It's a reliable, time-tested method using just a lighter. Here's how:

1. Warm the tip by holding a lighter flame nearby.
2. Run the flame gently along the pen's length to heat the ink evenly.
3. Caution: Don't overheat to avoid melting the plastic!
Your ballpoint pen works like new! :-)
