Permanent marker with a round tip for a strong line width of 1 - 3 mm. The ink color is blue. Ideal for marking and decorating rough and smooth surfaces such as paper, plastic, glass, ceramics, metal, leather, and rubber. The markings produced are highly opaque, with very good adhesion and abrasion resistance on nearly all materials. They are lightfast, water- and weather-resistant, resistant to many etching and washing processes, and heat-resistant up to 300 °C. The ink is controlled by a valve and is free from toluene and xylene. Individually packaged in shrink wrap, with a replaceable writing tip.
