Product Review

Pen features the same beloved thermos-sensitive ink that can be erased by FriXion. You can erase rub the thermos sensitive ink away using the cap. The pen writes smoothly and erases without a trace. 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. It is like a Magic pen for adults! because the ink in this pen is thermos 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 fruition.
