Simple filtering of unnecessary information. What is a highlighter for? We can find and emphasize the most important sentences. This way, we can better remember the information and quickly locate the highlighted facts, for example, in a speech or make a report clearer. Why is the Stabilo Boss Luminator Marker so helpful? The color of the marker does not obscure the text underneath. You can easily read what you have emphasized with the marker. Additionally, the color remains consistent throughout its usage. It does not fade even after a long time. Thirdly, thanks to the ink display, you can see how much ink is left in the marker. When the ink is almost depleted, you can easily purchase a replacement. Its liquid ink reservoir is larger than that of conventional highlighters.
