The MASTERPIECE 667PI Speedflow marker with the patented Flowmaster pump-valve and the exchangeable 15 mm Broad-Tip guarantees a constant ink flow.

The 367PI is filled with alcohol-based Speedflow black. 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.
