Uni-ball Propus Window Soft Color Double-Sided Highlighter Pen - 4.0 mm / 0.6 mm Twin Tip - Aqua Blue

What sets this highlighter apart from the others is the super cool transparent window on its tip that allows you to see where you're highlighting! The soft color series has lighter colors more pleasant to the eye than your standard fluorescent highlighter.

Plus, it is a combo highlighter that has a broad and fine tip - a 4.0 mm and 0.6 mm highlighter in one!
