Upgrade your writing with the precision and freedom of the Pilot FriXion Synergy Clicker Black Erasable Gel Ink Bundle. Engineered with Pilot’s hybrid Synergy Tip, this extra-fine 0.5mm pen combines the strength of a conical ball with the sharp accuracy of a needle point to prevent bending and skipping. Powered by thermo-sensitive gel ink, it allows you to write smoothly, erase mistakes cleanly using friction heat, and immediately rewrite over the same spot without paper tears, smears, or eraser shavings. Pack includes 5 pens and 3 refills with black erasable gel ink.
