Ballpoint pen Uni SXN-157S — Uni brand, red ink, retractable design

Uni SXN-157S is a Uni brand ballpoint pen with red ink and a retractable mechanism designed for everyday writing, note-taking and form filling. The pen features a smooth ballpoint tip and a lightweight plastic barrel that provides comfortable handling during extended use. Its retractable design protects the tip when not in use and makes the pen convenient to carry in pockets or organizers.

Advantages

The Uni SXN-157S delivers consistent red ink flow and reliable line performance suitable for corrections and annotations. The retractable mechanism eliminates the need for a cap and reduces the risk of ink drying on the tip. The plastic barrel keeps the overall weight low while providing a stable grip, and the visible ink color ensures clear contrast on paper.

Suitable for

• Marking corrections and annotations in documents and notebooks

• Office tasks, schoolwork and general home use
• Quick notetaking and making visible reminders

How to use
