The OTR 004 Soultip squeeze marker by On The Run is a new favorite for many writers. This versatile 75 ml squeezer is relatively small and easily concealable. It comes with a durable 12mm mohair "Diamond-Fibre" nib which won't tear when writing on rougher surfaces (like nylon tip squeezers). The Marker has a refillable 75 cl body, suitable for all ink and paint refills. For the perfect combination use ON THE RUN Soultip paint and Flowpen ink refills.
