Staedtler pigment liner 0.3, Art. Nr. 308 03-9, EAN 40 07817 330418
I had the ‘ex’ send me four of these from Iceland a couple years back, but am on the last one now, they don’t do to well in hot & dry situations. But otherwise, they are an excellent and clean substitute for my exploding Koh-i-noor India Ink drafting pens which were just too sensitive to changing air pressure (i.e., flying), and had to be totally disassembled and cleaned prior to any travel. The beauty of the line, and the feel of the metal tip on paper was superlative, but the hassle was too much for the traveler to bear.
