OTR.984 Flow Pen Ink (210ml) Black
OTR.984 Flow Pen Ink (210ml) Black
OTR.984 Flow Pen Ink is a high-performance alcohol-based refill system designed for serious marker work, experimental writing, and extended tool life. Developed by On The Run in Germany, this ink is engineered for consistency, durability, and compatibility across a wide range of refillable markers—including squeeze markers, steelball rollers, pump valves, brushes, and calligraphy systems.
It moves with a controlled fluidity—smooth enough for clean line work, yet bold enough to leave permanent, high-contrast marks across difficult surfaces like metal, glass, plastic, and stone.
This is not just refill ink. It is fuel for the system.
