Highlighter pens are marker pens that have a special ink designed to be seen through when writing over existing type, or writing. This is so that you can highlight areas of text that are of interest, or need to be brought to attention.
Highlighting is used extensively within offices, schools and at home, for example when revising for exams, and a highlighter pen is something that is often found in everyone’s top drawer. Nowadays you can have a wide choice of highlighter colours, and in all sorts of different sizes, meaning its easy to find the right one, whatever your needs. You can also buy highlighters that can be refilled with a highlighter refill
