This has never been seen before: The PenBookmark is a gel pen that is so flat that it can even be left in the book as a bookmark. The rollerball is ideal for taking notes because the thermo-sensitive ink can be erased and written over without leaving any residue. The new gel ink is thermo-sensitive and disappears from a temperature of around 60°C. The eraser heats the ink by frictional heat without damaging the paper, so the ink becomes invisible without leaving any residue. After some time in the freezer (-10 °C) the writing would appear again. The ink is therefore NOT indelible!
