The text marker is designed to work on all types of paper, including fax and copier paper. The chiselled writing tip allows for varying the width of writing. The wide part of the tip (5 mm) is convenient for highlighting... text, while the thin part (0.6 mm) is for underlining. The color of the body corresponds to the ink color. The fluorescent water-based inks dry quickly after application and do not leave marks on the back of the paper due to the thin and even application. It has a recognizable patented shape and has become an absolute bestseller in the ErichKrause range of text markers in more than fifty countries around the world.
