Frixion Ink by Gentian Osman

August 8, 2011 - Posted by Lucy to Felt / Porous Tip Markers

The ink of the Pilot FriXion pen is thermosensitive - it becomes clear when it is exposed to heat. This special video submitted by customer Gentian shows how the ink becomes transparent when exposed to heat from a tea kettle and reappears when exposed to cold air from a freezer. The Pilot FriXion line is available at JetPens available in a variety of different gel ink pens, markers and even highlighters! Read about our other erasable gel pens here.
