Zebra Sarasa Mark On Gel Pen – 0.4 mm – Red

If you’ve ever smudged carefully-written notes with a swipe of your favorite highlighter, the Sarasa Mark On is for you. It can stand up to highlighting after just five seconds on the page, with specially-formulated ink that has greater water resistance and adherence to paper than typical gel ink. The Mark On features Sarasa’s famous binder clip and a comfortable rubber grip.
