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.

And it'll just erase. Right off super handy. So that's a really great thing you don't feel like get it wet like the water-soluble. Ones or the air erase little ones that don't always come out this.

1,2 The ink from the FriXion pens is “erased” by a completely different phenomenon; the heat caused by friction between its hard, smooth plastic “eraser” and the paper containing the ink causes the thermochromic ink to turn colorless. This color change has also been found to be reversible.

It writes smoothly and erasable too. I recommend this pen to everyone. Especially people that are perfectionists because you don't have to write out or scratch notes. Just erase them.

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.

The Science Behind Erasable Ink Microcapsules that form the pigmentation contain an equal mix of three substances: leuco dye that can change between colored and colorless forms, color developer, and color change temperature regulator.

The Frixion pen contains a unique ink that is thermo-sensitive. When you rub the eraser on the end of the pen against the paper, you generate enough friction heat to turn the ink invisible (making it look like it has been erased).

#5 How do I remove ink from clothing? The FriXion pens do not contain permanent ink as it reacts to heat and becomes transparent.

How Does It Work. The friction pen uses ink that is sensitive to heat. At temperatures that range between 15°F and 140°F, the ink will appear black when writing on paper. But when local temperature exceeds 140°F, like when held near a heat source or when friction is concentrated on a certain spot, the ink becomes clear ...

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