Setup, Compatibility & Care
These highlighters are ready for use immediately out of the packaging. No priming is required. To maintain the life of your markers, always replace the cap securely after use to prevent the ink from drying out. Store the pens horizontally or with the cap facing down to ensure consistent flow. Since the ink is thermo-sensitive, keep documents highlighted with Frixion pens away from heat sources like radiators, heat lamps, or direct summer sun. If the ink disappears due to heat, you can often restore the writing by placing the document in a freezer for several minutes, though this is not guaranteed for all environmental exposures.
