The MASTERPIECE 460PI CoversAll is the shortest MASTERPIECE marker and perfect for your pocket. Equipped with the patented Flowmaster™ pump-valve and the exchangeable 15 mm Broad-Tip which ensures constant ink flow. The 460PI is filled with CoversAll cocktail ink. The pitch-black, alcohol-based ink contains a synthetic bitumen and guarantees a permanent, visco-plastic coating (signal black). It is also highly opaque, UV- and weather-resistant, quick drying, abrasion resistant and therefore perfect for indoor- and outdoor-use. Refillable with all of Molotow inks and paints, but for best results refill with the alcohol-based CoversAll refill cocktail.
