Maintenance
Cleaning
To maintain the pen's appearance, wipe the exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials, as these may damage the finish.
Storage
Store the pen with the tip retracted to prevent accidental marks and to protect the ink from drying out. Keep the pen in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
- Ink Not Flowing: If the ink does not flow smoothly, check if the refill is properly installed. Ensure the pen tip is clean. If the issue persists, replace the ink refill with one of the included spares.
- Pen Not Retracting/Extending: Ensure the top button mechanism is free from obstructions. If the mechanism feels stiff, gently press the button multiple times. Avoid forcing the mechanism.
- Pen Tip Appears Loose: Verify that the pen barrel is securely screwed together. If the tip still feels loose, ensure the ink refill is correctly seated and the spring (if applicable) is in place.
