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)
This 6 pen set includes: Coral Pink, Mauve, Lavender, Sky Blue, Emerald Green, and Honey Yellow.
