In 2005 Pilot created 'FriXion'. Today it is still the number 1 erasable pen on the market. FriXion uses unique thermo-sensitive gel ink which disappears once it reaches a temperature of more than 65 °C. This can be achieved by using the rubber attached to FriXion pen. The friction caused by rubbing the paper generates heat which causes the ink to become invisible. With no damage to the paper, you can erase and instantly re-write over your mistakes. The ink will reappear if you store your notes in a low temperature( below -10°C)
The Pilot Frixion Ball is part of the Frixion Series. It is a retractable erasable pen that allows you to write, remove and rewrite without the use of a correction tape.
Do not advise to use this pen on legal or official documents, examinations or mailing.
