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 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.
Note: this Ball Knock pen is the Japanese version of the Pilot FriXion Ball Clicker US Gel Pen, and differs in body style from the Ball Clicker. The Ball Knock Light Blue and Blue Black ink colors are the same as the Ball Clicker Turquoise and Navy ink colors, respectively.
