The pack contains 4 triangular highlighter in yellow, orange, pink and green. The pins fit because of their shape better in a pen holder, as the broad highlighter and can be kept well by the triangular shape. Depending on how you hold the pen he writes thick, medium or thin. This you can decide if you highlight a passage thick, or maybe would like to underline just thin. The colors are very nice and the pins do not smudge. I can only recommend.
