ZEBRA Sarasa Clip Gel Pen 0.3mm 5-Color Set

Buying Sarasa Clip as a 5-color set (JJH15-5C-N) is how most people start color-coding, and fixing every barrel at 0.3mm means your handwriting stays the same weight whichever color you pick up. At 0.3mm the line is fine enough for textbook margins, dictionary annotation and the small squares of a Japanese planner grid, which is why it is the size people with small handwriting buy on repeat. Five colors is the practical color-coding size: one for definitions, one for corrections, one for dates, and two left over for whatever a subject needs. Underneath, this is Zebra's standard workhorse: water-based pigment gel ink that flows without pressure, stays legible on cheap notebook paper and holds its color once dry, which is what lets you run a highlighter over your own notes without smearing them. The movable binder clip hinges open to grip a thick cover or a bundle of paper, and each pen takes a Zebra JF-0.3 refill in its own color, so the set outlasts the ink several times over. The JJH15 body code marks the 0.3mm size. Made in Japan by Zebra.

1. Assign each color a job before you open a new notebook - definitions, corrections, dates - so the set does real work instead of sitting in a pouch.
2. Click the knock to extend the 0.3mm tip and write with light pressure; gel ink is designed to flow without force, and pressing only wears the tip.
3. Retract the tip before dropping the pen in a bag so the point does not dry out or get bent.
4. When a color runs out, twist the barrel apart and fit a Zebra JF-0.3 refill in the same color rather than binning the pen.
5. If a pen hesitates after sitting unused, scribble a few loops on scrap paper to draw the pigment ink back down to the ball.
