Molotow CoversAll Speedflow Marker features a handmade, extra-broad 60mm tip. The alcohol-based colored ink is glossy, highly opaque and permanent, allowing for rapid-flowing color application. The color application is also said to "get a bit plastic" with the ink. The broad tip is suitable for calligraphy and fast working on large areas.
