POSCA PC-1MR Ultra-Fine Paint Marker – 16 pack: Ultra-Fine Precision for Artists
When your artwork calls for fine lines and precise details, the uni POSCA PC-1MR Ultra-Fine Paint Marker is an excellent choice. Combining the qualities of POSCA’s opaque, water-based pigment paint with a pen-style design, the PC-1MR gives artists, illustrators and designers excellent control over their linework.
Its ultra-fine 0.7 mm fibre tip is surrounded by a metal ring, helping produce clean, consistent lines and making the marker particularly useful when working with stencils or adding intricate details to artwork. The rich paint is ideal for defining outlines, adding fine accents, creating detailed patterns and finishing illustrations.
Unlike a conventional fine-liner, the PC-1MR delivers opaque paint rather than ordinary writing ink, making it a versatile tool for creative work across a range of materials.

How Does POSCA Paint Perform on Different Surfaces?
POSCA markers can be used on many different materials, but paint permanence depends on the surface.
| Surface | Suitable applications |
|---|---|
| Paper and cardboard | Technical drawing, illustration, lettering and fine details |
| Wood and stone | Decorative patterns, outlines and detailed artwork |
| Canvas | Fine outlines, small details and finishing touches |
| Glass and glazed ceramics | Decorative designs that can generally be removed from smooth surfaces |
| Metal and plastic | Fine detailing and customisation; test adhesion on the intended material |
How to Use Your POSCA PC-1MR Marker
- Shake the marker with the cap firmly attached to mix the paint.
- Remove the cap and gently press the tip against scrap paper until the paint begins to flow.
- Test the marker before beginning your artwork to check the paint flow and line quality.
- Use light, controlled strokes for the finest and most consistent results.
- Allow the paint to dry between layers and replace the cap securely after use.
POSCA PC-1MR vs PC-1M: What’s the Difference?
| Feature | PC-1MR | PC-1M |
|---|---|---|
| Tip design | Calibrated tip with metal ring | Fine bullet tip |
| Tip size | 0.7 mm | Approximately 0.7 to 1 mm |
| Main advantage | Consistent, precise lines | Flexible control for detailed drawing and small areas |
| Ideal uses | Technical drawing, stencils, fine outlines and small lettering | Illustration, detailed colouring, card making and general fine work |
Both markers are designed for fine detail, but their tips are constructed differently.Choose the PC-1MR when precision and consistency are your priorities, particularly for technical work, stencil use and very fine outlines. Choose the PC-1M when you prefer a traditional bullet tip for detailed drawing and small areas of colour.
