Kokuyo Mark+ Dual Tone Highlighter / Island Color Set
With Kokuyo's Mark+ Two Tone highlighter, you can highlight with two colors easily. The tip of the highlighter separates into two tips in two colors. One with brightly colored ink and one with a softer shade of the same color. Simply rotate the highlighter in your hand to change colors. You can use the different shades to distinguish your most important highlights from the rest, or you can use them to color-code your notes while keeping them clean-looking and harmonious.
The Island Set consists of 3 colours (each colour in two shades): Island Sky Blue, Island Leaf Green, and Island Coral Pink.
