POSCA PC-3M Fine Paint Marker – 8 Pack: Fine Lines, Bold Possibilities
Looking for a paint marker that can handle both detailed linework and small areas of colour? The uni POSCA PC-3M Fine Paint Marker – 8 Pack is a versatile choice for artists, illustrators, designers and creative makers.
Featuring a fine bullet tip with a line width of approximately 0.9 to 1.3 mm, the PC-3M strikes a useful balance between precision and coverage. It is fine enough for controlled outlines and detailed illustration, yet broad enough to fill small shapes, create decorative lettering and add confident colour accents to artwork.
The water-based pigment paint produces opaque, matte marks with strong coverage. Unlike an ordinary felt-tip marker, POSCA uses paint, making it suitable for a wide range of creative applications across different materials.
Whether you’re adding crisp outlines to an illustration, decorating a journal, personalising an object or finishing a mixed-media painting, the PC-3M is a handy all-rounder for your art supplies collection.

How Does POSCA Paint Work on Different Surfaces?
POSCA PC-3M markers can be used on a wide variety of materials. The paint’s permanence depends on the surface and any protective treatment applied.
| Surface | Suitable applications |
|---|---|
| Paper and cardboard | Drawing, illustration, lettering and decorative details |
| Canvas and wood | Fine outlines, accents and surface decoration |
| Stone | Rock painting, patterns and lettering |
| Glass and glazed ceramics | Decorative designs that can generally be removed from smooth surfaces |
| Metal and plastic | Customisation, lettering and decorative artwork |
| Fabric | Decorative designs; test first and check suitable care and fixing instructions |
POSCA paint is generally permanent on porous surfaces once dry, while it can usually be removed from smooth, non-porous surfaces. If your finished work needs to withstand handling, moisture or outdoor exposure, test the paint first and check the appropriate sealing requirements.
How to Use Your POSCA PC-3M Marker
- Shake the marker well with the cap firmly attached.
- Remove the cap and gently press the tip against scrap paper until the paint begins to flow.
- Test the marker before starting your artwork to check the flow and coverage.
- Allow the paint to dry between layers when adding details over existing colours.
- Replace the cap securely after use to protect the tip.
