Pilot FriXion pens are truly unique. Highly effective erasable pens with incredible heat-sensitive ink. Heat generated by the friction of the eraser causes the ink to become clear. No mess, no dust, no paper damage and completely 'erased' lines. You can then re-write using the same pen. Now available in standard rollerball, needle-point roller, retractable Clicker, premium metal-barrel Slim version - all in up to 8 ink colours plus the Frixion Light highlighter. A truly revolutionary pen range. Ideal for school and perfect easy-correct pens for dyslexics!
How does it work? Metamocolor technology! 'Metamocolor' is a word entirely made up by Pilot marketing people, but basically it's a type of thermo-reactive ink. The heat generated by the friction causes the ink to become translucent (at 65°C fact-hounds!). Stick it in the freezer (<20°C) and your scribblings will re-appear - albeit slightly faded. Ideal for secret messages and a lot easier than that old lemon juice and candle flames malarkey.
