Key specifications
 Tip size: 0.4 mm (fine)
 Ink color: blue
 Pack quantity: 10 pens
 Ink type: water-based pigment ink for steady flow and quick drying
 Barrel: slim, lightweight design for comfortable grip
 Cap: snap-on compact cap to protect the tip and prevent drying
How to use
Remove the snap-on cap before writing and place the cap back on after use to maintain ink freshness. Hold the pen at a comfortable angle and apply light to moderate pressure for a consistent 0.4 mm line; heavier pressure may widen the stroke. Use on standard paper, notebooks and drafting paper. For technical drawing, pair the fine-liner with rulers and templates to achieve straight lines and precise details. Store pens horizontally or with the tip down for short-term storage to support steady ink flow.
Usage recommendations
For best results, allow fresh ink lines to dry briefly before stacking pages to minimize transfer. When working on archival or ink-sensitive documents, test the ink on a scrap sheet to confirm compatibility. Replace pens from the pack as needed to maintain consistent line quality across projects.
