- Holding the Pen: The ergonomic triangular barrel is designed for a comfortable and natural grip. Hold the pen as you would a standard writing instrument.
- Writing/Drawing: Apply light to moderate pressure to the paper or desired surface. The superfine tip produces a consistent line of approximately 0.3mm.
- Capping: After use, always replace the cap firmly with a click to protect the tip and prevent accidental marks. While the pens feature DRY SAFE technology, proper capping extends their lifespan.

- Cap Replacement: Always replace the cap securely after each use. The ventilated cap meets ISO 11540 standards for safety.
5. Troubleshooting
If you encounter any issues with your fineliner pens, refer to the following common solutions:
- Pen not writing or ink flow is inconsistent:
- Ensure the cap has been removed.
- Gently try writing on a scrap piece of paper to re-prime the tip.
- If the pen has been left uncapped for an extended period beyond the DRY SAFE limit, the tip may have dried out. Consider replacing the pen.
- Ink appears faded:
- The ink level may be low. Replace the pen with a new one.
- Accidental ink stains on clothing:
- Due to the water-based ink, most stains can be washed out of textiles. Treat the stain promptly with water and a mild detergent.
