Uni-ball Erasable Retractable Rollerball Pen 5-Piece Set Red Blue Black Green Pink And Violet

The Uni-Ball Erasable Gel rollerball uses a specially-formulated ink. Simply by rubbing the ink line with the cap of the pen, enough heat is generated to turn the ink clear, 'erasing' the line cleanly. The same pen can then rewrite over the erased lines. Erased lines will reappear if subjected to very low (-18 °C) temperatures.

When erasing, the ink initially disappears much quicker than other erasable pens. Don't be fooled though - a little extra heat is still needed at this point to stop the ink colour from coming back: just give the writing a couple of extra rubs and it'll be invisible for good (unless you put it in the freezer of course).

Set of five pens includes: Red, Blue Black, Green, Pink, Violet
