## Long description

INTERDRUK TRI-X Color oil-based ballpoint pens in blue ink, pack of 50. Each pen is equipped with oil-based ink designed for smooth, consistent writing and reliable lines on standard paper.

Advantages
The oil-based ink formulation reduces skipping and provides uniform ink flow for continuous lines.

Blue ink dries quickly on typical paper to minimize smudging and deliver legible results for forms, notes, and documents. The consistent performance across the set simplifies inventory and replacement planning.

 Filling forms, signing documents, and record keeping
 Everyday note-taking and list-making

How to use
Remove a pen from the pack and extend the tip if the model requires it; hold the pen at a comfortable angle and apply light to moderate pressure for regular ballpoint writing. Use on standard paper surfaces for best results. Store unused pens capped and horizontally or tip-up in a cool, dry place to maintain ink flow and prevent drying at the tip.
Usage recommendations
For consistent performance, use these pens on standard office or school paper and allow a brief moment for the ink to dry before stacking or filing documents. Replace pens from the pack as needed to maintain a ready supply for frequent writing tasks.
