Product Information
Full details
The Muji Coloured Gel Pen with a 0.5mm tip is designed for students, office professionals, and journal enthusiasts who prioritize a smooth writing experience and precise line control. This pen delivers a reliable ink flow that makes note-taking and creative tasks enjoyable, though the cap-based design means it may not be as convenient for rapid, one-handed deployment compared to retractable models.

FAQs
Is the ink waterproof?
Muji gel ink is generally water-based; it is not typically marketed as waterproof or archival-grade.
Does this pen bleed through thin paper?
On most standard notebook paper, the 0.5mm tip produces a clean line with minimal bleed-through, but results may vary on extremely thin newsprint or parchment.
Can I refill this pen?
The Muji gel pens are designed primarily as disposable stationery; while some ink components are integrated, it is generally recommended to replace the entire pen.
Is the 0.5mm tip good for drawing?
Yes, the 0.5mm size is excellent for technical drawing, outlining, and detailed sketching due to its consistent line width.
Why is there a cap instead of a click mechanism?
The cap is specifically designed to provide an airtight seal, which is necessary to keep the gel ink from drying out within the precision nib.
Troubleshooting
The pen is not writing despite being new.
Check to ensure the small plastic protective seal on the nib tip has been removed.
Ink flow is inconsistent or skipping.
Try scribbling in small circles on a scrap piece of paper to restart the ink flow through the ball mechanism.
Ink smudges on the page.
Allow a few seconds for the gel ink to dry, or use a higher quality, more absorbent paper stock.

Setup, Compatibility & Care
This pen is ready to use immediately upon removing the protective tip seal, which is often found on new units to prevent leakage during transit. To maintain the pen's longevity, ensure the cap is snapped firmly into place when not in use; this prevents the gel ink from thickening or drying out at the nib. While the pen is compatible with most paper types, avoid using it on glossy surfaces or labels where the gel ink may not adhere properly and could smudge. If storing for long periods, keep the pen upright with the cap facing upward to maintain optimal ink distribution.
