Mini version of the On The Run OTR.069 Stainless Flowpen 20mm. The pen, which only measures 10cm with the cap on, is filled with a “Dirty Chrome” colour that is a mix of silver and black ink. The ink is a permanent, and alcohol based ink mix that looks like stainless steel once it’s dry. The pen has a 20mm wide tip, and you control the flow of ink by pumping the tip against your surface. Refillable and with a changeable tip.
