On The Run OTR.071 Cold Sweat Ink Marker 20 mm

One of our favourites! A flowpen filled with black permanent ink that has bitumen mixed into it, to give it a thicker, more creamy consistency. You control the flow of ink by pumping the tip against your surface. The tip is 20 mm wide and is easily changeable if needed. Just like most of the other On The Run pens, this is refillable.
