Pen — Tetis automatic ballpoint pen KD 940 NM, refill blue 0.5 mm, mixed barrel colors

Tetis KD 940 NM is an automatic ballpoint pen supplied with a 0.5 mm blue refill. The retractable mechanism protects the tip when not in use and the fine 0.5 mm point delivers controlled, precise lines for everyday writing, note-taking and office tasks. The pen is offered in mixed barrel colours, providing a simple, low-maintenance option for classrooms, workplaces and home use.

Advantages

This automatic ballpoint pen provides a fine 0.5 mm writing tip that balances smooth ink flow with detailed line control. The retractable design avoids accidental ink marks and eliminates the need for a cap. Compatible with refill-based use, the pen reduces waste and allows continued use after the initial refill is spent. The mixed-colour barrels help with quick visual identification in shared settings.

Suitable for

• Everyday handwriting and note-taking
• Office documentation and form filling
• Schoolwork and study notes
• Labeling and light drawing with a fine point

Key specifications

• Tip size: 0.5 mm fine point
• Ink colour: blue
• Mechanism: retractable (automatic)
• Body: mixed-colour barrels
• Refillable: yes, uses replaceable ink refill

How to use

Press the retractable mechanism to extend the 0.5 mm tip before writing and press again to retract it after use. Write with moderate pressure to maintain consistent ink flow and avoid pressing excessively, which can damage the tip or cause thicker lines. Replace the refill when ink runs out by unscrewing or pulling apart the barrel according to the construction of the specific barrel colour variant, inserting the compatible refill and reassembling the pen.

Usage recommendations

Store the pen horizontally or with the tip retracted to prevent accidental ink marks. For best results on standard paper, use light, steady strokes and keep a spare compatible blue 0.5 mm refill available for uninterrupted use.
