Ballpoint pen BIC 829158 — clip-on retractable, blue ink, transparent barrel, pack of 12

Gel ink retractable pen with a medium 0.7 mm tip and a 0.35 mm line width, designed for smooth, bright writing. The pen uses water-based gel ink and a tungsten carbide ball for consistent ink flow and long-lasting performance. The transparent tinted barrel matches the ink color and allows you to monitor the remaining ink. The pen includes a rubber grip and a click retractable mechanism for ease of use. The product is PVC free.

Advantages

The gel ink provides ultra-smooth writing with vivid colors while requiring very low pressure. The tungsten carbide ball ensures durability and a steady ink flow. A rubber grip offers comfort and improved control during extended use. The clear tinted barrel lets users quickly check the ink level, and the retractable clic mechanism protects the tip when not in use.

How to use

Press the click mechanism to extend the tip before writing and press again to retract it after use.

Recommendations

Store the pen horizontally or with the tip up when not in use to help maintain consistent ink flow. Avoid exposing the pen to extreme heat or direct sunlight to preserve ink quality.
