Description The LKFBS-60EF Frixion Ball 3 multi-color Frixion pen is 3 erasabale Frixion Ball gel ink pens in one. The pen has black, blue, and red inks. The Frixion Ball 3 pen has a soft rubber grip for comfortable writing. The durable lift-clip holds tight even on thick fabric or objects thanks to its coil spring. If you prefer, you can string a chain through the hole in the clip and hang the pen from your bag or from your neck with your ID. The revolutionary “Frixion” ink is a thermo-sensitive gel ink. The color of the ink becomes colorless (“disappears”) due to the heat generated by friction when rubbing the rubber tail plug of the pen on the paper. The writing is erased without debris. Frixion-series pens can write repeatedly on the same spot with the same pen. NOTICE – As with any non-permanent or erasable writing instrument, do not use on legal or official documents. – Frixion ink becomes colorless (becomes “erased”) upon reaching 60℃. To restore color, cool to -10℃ in freezer. Restored writing may be smudged and fainter than the original writing.
