FAQs
What surfaces can I use the Uni-Ball POSCA PC-5M on?
You can use it on virtually any surface, including paper, card, metal, glass, plastic, textiles, and more.
Is the ink permanent?
The ink is permanent on absorbent media like paper and card. On other surfaces, permanence depends on the treatment applied (e.g., heat or varnish).
How do I make the ink permanent on glass?
Bake in the oven at 160°C for 45 minutes, then spray with clear varnish.
How do I care for my POSCA marker?
Always replace the cap tightly after use and store the marker horizontally.
Can I remove POSCA ink?
Yes, on shiny surfaces, you can remove the ink with a scraper. However, on absorbent media, the ink is permanent.
What is the stroke width of the PC-5M?
The stroke width is approximately 1.8 - 2.5 mm.
What should I do if my marker dries out?

Troubleshooting
Marker isn't writing or the ink flow is poor.
Shake the marker well with the cap on and prime the nib by pressing it onto a surface a few times. If the problem persists, try storing the marker horizontally.
Ink is fading or smudging.
Ensure the surface is clean and dry before applying the marker. If the surface is non-absorbent, allow the ink to dry completely and consider using a sealant or the appropriate heat treatment.
The marker is skipping or the line is inconsistent.
The nib might be clogged. Try wiping the nib with a clean cloth or tissue. If that doesn't work, consider using a replacement nib.
