Pilot FriXion Ball Slim 038 ultra fine retractable erasable pen features its thermo-sensitive ink that can be erased by friction.
The special rubber tip at the end allows you to erase conveniently without having to cap or uncap your pen.
The pen writes smoothly and erases without a trace! Refills available for select ink colors.
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.
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.
We also do not advise to use on writing in examination and signing documents and cheques.
