"Frixion Point Knock 04" is an ultra-fine erasable ballpoint pen that realizes smooth writing and smooth writing by taking advantage of the features of "friction" that disappears when rubbed and the features of "synergy tip".
The ultra-fine 0.4 mm pen tip makes it easy to write on small parts such as notebooks and materials, and the erasing rubber on the back of the pen has a slim shape, making it easy to erase small parts. With a slightly slim shaft diameter of 10.5 mm, it is easy to store in a notebook or suit pocket.
* Friction is an erasable writing instrument. Please do not use it for things that cannot be erased, such as certificates and addresses.
