Pilot FriXion pens use a unique “Thermo-sensitive” ink which provides the benefit of being erasable by applying heat. This ink is very different to that which would be found in other ballpoint or rollerball pens and more of the ink needs to be applied to the writing surface.

FriXion ink “erases” due to Pilot's exclusive thermo-sensitive ink technology. If you need to make corrections on the page, simply “Frixion-It” by rubbing with the FriXion eraser tip as if using a regular pencil eraser. When rubbing, the ink heats up to over 60°C and becomes invisible.

The Frixion pen is made by Japanese stationery maker Pilot, which is famous for its erasable ink.

The ink in FriXion pens is made of a three-component system. Contained in microcapsule particles with a diameter of 2-3 µm (For reference, that's around 25 times smaller than the width of a human hair) are a leuco dye, a colour developer, and a colour temperature adjusting agent.

It's a great erasable pen. The top of the pen contains the rubber tip used for erasing, which is convenient and works well.

Erasable pens are great for people who prefer to erase writing instead of crossing it out. Similar to pencils, the impermanence helps keep notes tidier and more orderly, except that erasable pen ink doesn't smudge after you're done writing.
