The Uni Paint Marker PX-20 is an oil-based permanent marker with bold, opaque coverage that sticks to almost any surface — paper, glass, metal, wood, ceramic, stone, and more. The Orange ink is quick-drying, water-resistant, and fade-proof, making it handy for craft projects, labelling, and DIY work. The bullet tip provides smooth, consistent lines, and the valve-action control keeps the flow steady from first use to last.
