Set #2 of 4 calibrated Blackliner Molotow markers MOLOTOW BLACKLINER is the perfect waterproof fine tip marker with permanent ink. The water-based fine tip markers were developed in cooperation with Schneider Schreibgeräte GmbH. In addition, the ink is resistant to chemicals, fading and smearing in combination with water- and alcohol-based inks. Therefore, the fine tip marker pen is perfectly suitable for sketches, contours, fine lines and precise illustrations such as graffiti sketches, comics and tattoo motifs. Includes different tips: 0.3 mm., 0.5 mm., 0.7 mm. and 1 mm.   Thanks to their "Cap off" function, the waterproof fine-tip markers are protected from drying out for 90-180 minutes*. *1.0 mm stroke width = 30 minutes.
