A highlighter with liquid ink has enlarged ink capacity due to the Free ink technology. A highlighter for marking text on all paper types including fax and copying papers. The highlighter has a flattened barrel with a soft rubber coating, translucent cap and a transparent ink level window. The chisel-shaped tip allows to vary the writing width. The wide part of the tip (3.0 mm) is convenient for highlighting text, and the thin part (1.0 mm) is for underlining. The color of the cap and the front body part match the ink color. The fluorescent water-based ink dries quickly after emission and does not leave marks on the back of the paper thanks to thin, even drawing. The shelf life is 5 years. Maximum writing length is 500 м.
