Uni-Ball Posca PC-1M Marker - Yellow

The POSCA PC-1M Uni is a water-based marker with a 0.7 mm extra-fine tip designed for precise detail, outlining, and coloring. It features a cylindrical plastic body, a valve mechanism to seal the ink, and a mixing ball that helps blend ink for uniform coverage. The marker delivers intense, opaque colors and writes on a wide range of surfaces, including paper, wood, glass, metal, plastic, and ceramic. The ink is water-based, can be diluted or mixed while wet for gradients or new shades, and layers can be added after previous ones dry. Colors are UV resistant and the marker supports a variety of techniques, from fine drawing to signage and decorative accents. Shake to activate, press the tip to start ink flow, and cap when not in use to avoid drying. For versatile applications, the PC-1M is suitable for illustration, design, personalization, and crafts across different skill levels.

Usage and surfaces

Shake the marker to activate the paint. Remove the cap and press the tip on a sheet until the ink flows smoothly. Use on paper, wood, metal, glass, plastic, ceramic and more for detailed drawings, coloring, and lettering. Replace the cap after use and keep the marker horizontal when not in use to prevent drying. The ink is permanent on porous surfaces and non-permanent on glossy surfaces, and it can be diluted to create gradients while wet. The marker supports techniques like color blending, layering, and light “blowing” for airbrush effects.
