A brand name for erasable ink pens that use friction and heat to remove writing, blending 'friction' and 'eraser.'
Modern coinage by the Japanese stationery company Pilot, combining 'friction' (Latin frictio) with a suffix suggesting erasure, creating a portmanteau for their heat-reactive ink technology.
Frixion pens are genuinely magical—the ink isn't actually erased, just made invisible through heat until friction from the eraser warms it back up, making the writing reappear if you accidentally freeze it!
