Highlighters are invaluable study aids and reading tools, but nothing undermines their effectiveness like accidentally highlighting the wrong thing. With Pilot Frixion Highlighter, however, that's no problem! Simply use the rubber "eraser" tip at the top of the highlighter. The ink disappears cleanly, and there are no eraser shavings. After trying a FriXion highlighter, you'll wish every highlighter you owned was erasable.
