On The Run OTR.171 Cold Sweat Mini Ink Marker

Mini version of the On The Run OTR.071 Cold Sweat Ink Maker 20mm. Like its bigger brother, this pen is filled with On The Run’s Cold Sweat ink, an alcohol-based black ink that has been mixed with bitumen, which gives it a more oily consistency. The pen is small and flexible and has an extra wide 20 mm tip. New tips are sold separately and the marker is refillable.
