Pilot Frixion Erasable Rollerball Pen Medium – 0.7mm tip.
Pilot’s Frixion erasable rollerball has clever ink which turns transparent when subjected to friction.
No eraser dust, and the line disappears very cleanly leaving only a faint impression of the erased line.
You can use either the eraser end, or any hard plastic.
Useful to use the capped end instead of the eraser when working on newsprint for crosswords or Sudoku
