The Masterpiece 667PI Speedflow marker features the patented Flowmaster pump-valve and a 15mm broad tip which ensures a constant ink flow.

The 667PI marker is filled with alcohol-based Speedflow black ink. The black cocktail Speedflow ink on nitrogen-based paint 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 with all Molotow inks and paints but for best results we recommend refilling with the alcohol-based CoversAll and Speedflow refill cocktails.
