Product Features:
Friction with synergy tip for smooth writing
"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".
"Synergy tip" is a "pipe tip" that has a structure in which the tip of an ultra-fine stainless steel pipe suitable for fine writing is provided with a dent to support the ball with a point, and a conical tip used for general ballpoint pens. It is a tip with a structure and shape that makes the best use of each feature of the "cone tip", which is strong, stable and easy to write. Therefore, while the pen tip is ideal for fine writing, the strength of the pen tip is high, the ink supply is smooth, and smooth writing is possible.
Ultra-fine 0.4 mm pen tip ideal for small parts such as notebooks and materials
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.
The body design uses metal clips and bases for a luxurious finish. With a shaft diameter of 10.5 mm, which is slightly slimmer than the "friction ball knock", it is easy to store in a notebook or suit pocket.
Features of the friction series:
[Transparency of handwriting
due to temperature change ] A new concept ballpoint pen equipped with "friction ink" that makes ink colorless by temperature change. Since the decoloring temperature is set for "friction ink", the color of the ink changes to colorless due to the frictional heat generated by rubbing the handwriting with the special rubber at the rear of the body, and the handwriting can be erased.

[Erasing residue does not appear. There is little erasing residue]
Unlike writing instruments that are erased with an eraser, the ink in the handwriting is made colorless by frictional heat, so there is no erasing residue. Another feature is that there is very little unerased residue compared to the erased marks of pencils and mechanical pencils.

[Can be erased as many times as you
like ] Unlike chemical formulas such as ink eraser, you can write repeatedly at the erased part.
