FriXion Synergy 3 is a three-color erasable pen from Pilot: black, red and blue in one slim body, all at 0.4 mm. Write, rub it out with the rubber tip, and write again.

What sets it apart is the Synergy tip. A pipe tip writes thin and smooth, and a cone tip holds plenty of ink and stands up to pressure, so Pilot put the two together. You get a fine 0.4 mm line that still glides, and it won the function prize at Japan's 2026 Stationery Awards.

Why people love it
- Fine enough for planner boxes and small handwriting, and still smooth
- Three erasable colors, so your color-coding can change when your plans do
- A clean, angular body and a metal clip, as at home in a meeting as in a pen case
