Karin DecoBrush Metallic Brush Pens contain 2.4 ml of non-toxic paint based on metallic pigments. They work beautifully on both black and white surfaces. They are produced using "liquid ink" technology which means that you can make the most of every last drop of ink.
Metallic paint, once dry, is permanent, light-resistant and waterproof on surfaces such as paper, wood, ceramics, glass, metal, plastics.
