Writing, rubbing, correcting - all with just one rollerball pen! With the FriXion Ball from PILOT, small mistakes can be corrected quickly and neatly. This definitely makes it a must-have for anyone who wants to be flexible! The innovative, thermosensitive ink disappears when erased. All you have to do is briefly rub the plastic tip at the end of the rollerball's casing over the paper. The frictional heat generated (from approx. 60 °C) ensures that the writing disappears. Erased too much? No problem either! Cold causes the reverse effect. Place the paper in the freezer for a short time (from approx. -10 °C) and everything will appear again - as if by magic!
