PILOT Frixion Point Knock Ballpoint Pen 0.4mm Set

Friction with synergy tip for smooth writing

"Friction Point Knock 04" is an ultra-fine, erasable ballpoint pen that utilizes the features of "Friction" that disappears when rubbed and the features of "Synergy Tip" to achieve smooth writing and smooth writing.
"Synergy tip" consists of a "pipe tip", which has a structure that supports the ball at a point by adding a hollow to the tip of an ultra-fine stainless steel pipe suitable for fine writing, and a conical shape used for general ballpoint pens, which increases the tip strength. It is a chip with a structure and shape that takes advantage of the features of each of the "corn chips" that are strong, stable and easy to write. As a result, while the nib is ideal for fine writing, the nib's strength is high, and the ink supply is smooth, allowing for smooth writing.

Features of the friction series

[Feature 1] Handwriting becomes transparent due to temperature changes! 　
A new concept ballpoint pen equipped with "friction ink" that makes the ink colorless due to temperature changes. Friction Ink has a set erasing temperature, so the frictional heat generated by rubbing the handwriting with the special rubber on the back of the body turns the ink colorless and the handwriting can be erased.

[Feature 2] Eraser residue does not appear. There is little residue after erasing.
Unlike writing instruments that erase with an eraser, the frictional heat makes the ink colorless, so there is no eraser scum. Another feature is that there are very few unerased marks compared to erased marks of pencils and mechanical pencils. [Feature 3] You can write and erase any number of times. Unlike chemical formulas such as ink erasers, it is possible to repeatedly write on the erased area. [How to use] After the handwriting is dry, rub it with the rubber on the back of the shaft to erase the color. *Cannot be used for proof documents and address writing.

 *The color will disappear if rubbed with a special rubber.

*Please do not use it for items that should not be erased, such as certificates and        addresses.
*Do not place in direct sunlight or places with high temperatures. At 60℃ or higher,    the ink becomes colorless.
*Erased handwriting may return at around -10°C.
* Do not use for writing on anything other than paper.
* Depending on the type of paper, such as thermal paper, and the characteristics of    the printed matter, it may not be suitable for erasing.
* If you rub the erase rubber with dirt on it, the paper will get dirty. Please use it          after removing the dirt such as wiping off.
