Interestingly enough, the ink in these pens will actually reappear when the temperature reaches below -10 C (under 14 Fahrenheit). A freezer is sufficiently cold enough to make the ink start to reappear, you can watch a video on how it works here. It is like a magic pen for adults!
Because the ink in this pen is thermo sensitive, we do not advise for it to be left in hot cars, used for mailing, or subjected to a condition that exposes it to a lot of friction.
The video below demonstrates how well these pens erase:

Bought for my math teacher...
Bought for my math teacher cause we do work projected on the screen, instead of scribbling out mistakes---he can erase. Hope he likes it. I tested it out and I love it!
