FriXion Ball Clicker 0.7 - Black

Clicker Ball 0.7 Black in the FriXion series from Pilot Pen. These are erasable ballpoint pens with heat-sensitive ink. Clicker means that the pen has a clicker function that is on the pen's clip, you don't have to use a pen with a cork. The tip ball diameter is 0.7 and the line width when writing is 0.35 mm.

You erase text by erasing with the tip of the pen and the friction creates heat, which erases the ink. But this in turn means that both ink and pens are sensitive to heat and cold, for example a hot car or the sun. You can get the erased text back by putting it in the freezer, but then everything you erased will appear again.
