The MASTERPIECE 467PI Speedflow is the shortest MASTERPIECE marker and perfect for your pocket. This MASTERPIECE marker in pocket format with the patented Flowmaster™ pump-valve and with the exchangeable 15 mm Broad-Tip ensures a constant ink flow. The 467PI is filled with alcohol-based Speedflow cocktail ink. The contained, nitrogen-based, black cocktail Speedflow ink has a visco-plastic coating with a light copper shimmer (chemical black). It is highly opaque, UV- and weather-resistant, fast drying, abrasion resistant and suitable for both indoor- and outdoor-use. Of course, it's refillable very easy with all of our inks and paints. But the best results you´ll get with the alcohol-based CoversAll and Speedflow refill cocktails.
