Pentel E-Ball Retractable Ballpoint Pen - Black - 1.0mm Tip

The Pentel E-ball Medium has a 1.0mm tip, which creates a medium line width. The actual visible line width is approximately 0.5mm.

This pen uses smooth oil-based ink, known for its consistent flow and vivid color.

Yes, the Pentel E-ball Medium is refillable and uses the Pentel BKL10 refill.

Over 70% of the pen's body is made from recycled materials, as part of Pentel's Recycology range.

You extend and retract the pen tip by clicking the button at the top of the pen. Click once to extend, and click again to retract.

The E-ball series is available in black, red, and blue ink colors.

While it's excellent for general writing, the 1.0mm tip is quite broad for detailed drawing or fine art applications. It's better suited for sketching or bold lines.

Ensure the tip is extended properly. Check if a refill is needed. If refilling, ensure the refill is inserted correctly. Try scribbling on a scrap piece of paper to re-engage the ink flow.

The pen may be running low on ink. Consider replacing the refill. Ensure you are not pressing too hard, which can sometimes disrupt ink flow.

Gently try to retract and extend the tip multiple times. Avoid forcing it. If it remains stuck, the internal mechanism might be damaged, and it may be time to replace the pen.

Allow the ink to dry for a few seconds before touching or highlighting over it, especially on glossy paper. For left-handed writers, consider using a faster-drying pen or holding the pen at a different angle.
