Write smoothly and with the unique thermo-sensitive gel ink you can now erase every word completely from the page by using the rubber tail plug on the lid of the pen without any wear or tear to the paper or messy eraser crumbs. 
 
*Note: Erasable pens are not recommended for use on legal or office documents. Do not expose to extreme temperatures (<14 ℉;>140℉) If pen is exposed to temperature that reaches 140℉, the ink will be colorless when writing. To restore color, cool to at least 14℉ freezer and the ink will again write in color.
