Fine point: 0.7mm tip; ink color: blue; ink type: low-viscosity Butter Flow; drying time: quick-drying; grip: patterned barrel for better control; pack size: box of 12 pens.

Yes. The ink is designed to dry quickly on standard copy paper, helping to minimize smears on notes, forms, and printed documents.

Ideal for school notes, office forms, forms completion, writing in notebooks, and everyday writing tasks where clear, consistent lines are important.

Use the pen as you normally would for writing. When not in use, cap it (if it has a cap) and store at room temperature away from extreme heat or moisture. If the ink seems to skip at first use, write on a scrap page for a moment to primer the tip.

This product is sold as a disposable box of pens. Once the ink runs out, you would replace the pen with a new one rather than refilling the same pen.

The pen is intended for ordinary school and office use. It is non-toxic and suitable for everyday writing. Keep away from small children who might chew or swallow the components, and avoid ingestion of ink.

This 12‑pack offers a low-cost per-pen option with consistent 0.7mm performance and quick-drying blue ink, making it a strong value for students and professionals who write frequently and want dependable, smooth strokes.
