Zebra Z-Grip Smooth Retractable Ballpoint Pen - Pack of 5 - Black

The ink is not specifically waterproof, but it is designed to be water-resistant. Exposure to water may cause smudging.

No, the Zebra Z-Grip Smooth Retractable Ballpoint Pen is not refillable. You will need to replace the entire pen when the ink runs out.

The pen has a 1.0mm tip, which produces a 0.6mm line width.

It has a rubber grip for added comfort.

This guide focuses on the black ink version. Other colors may be available in different product variations.

Store the pens with the tip retracted when not in use, and keep them away from extreme temperatures and direct sunlight to prevent ink leakage.

Ensure the pen is retracted. Check if the tip is blocked, and try writing on a different surface. If ink is still not flowing, the pen may be out of ink.

Make sure you are applying consistent pressure. Try writing at a different angle. If the problem persists, try a new pen.
