Pilot Pen-FriXion Light Pastel Highlighter. The highlighter that you can erase! Simply use the rubber eraser tip at the top of the highlighter. The ink disappears cleanly, and there are no eraser shavings. FriXion ink is a thermos-sensitive ink that can be erased by rubbing. Interestingly, erased ink reappears at temperatures below 14 degrees Fahrenheit. It is advised against using FriXion for mailings, or leaving written materials in hot cars or in environments that expose them to a lot of friction. Contains one 5- 1/2x1/2 inch pastel highlighter. Comes in a variety of colors. Imported.
