Refill for Friction Ball Pen
Product Features
Erasable Friction Ball Pen Refill
Features of the Friction Series
【Feature 1】 Text disappears with heat!
Equipped with "Friction Ink" that becomes transparent with temperature changes. The "Friction Ink" has a set erasing temperature, so by rubbing the dedicated rubber at the back of the pen body with friction heat generated during rubbing, the ink color changes to transparent, allowing you to erase the writing.
【Feature 2】 No eraser debris, minimal residual marks.
Unlike traditional erasing tools, the ink becomes transparent through heat, so no eraser debris is produced. Additionally, residual marks are very minimal compared to pencil or mechanical pencil erasures.
【Feature 3】 Repeated writing and erasing possible.
Unlike chemical erasers, you can write over erased areas multiple times.
【Usage】 After the ink has dried, rub with the rubber at the back of the barrel to erase the color. *Cannot be used on certificates or for addressing.
New feature "ZONE TECHNOLOGY"
The "Friction Ball Knock Zone" is a next-generation erasable pen that responds to user requests for darker lines and increased ink capacity, allowing for "darker and longer" writing.
Introduction of "ZONE TECHNOLOGY"
① Version 2 (V.2) refill (using "Premium Friction Ink")
In response to user requests for darker lines and more ink, a newly developed "Premium Friction Ink" is used in a metal refill. The "Premium Friction Ink" has a 30% higher ink concentration in black and 15% higher in red and blue compared to conventional "Friction Ink," enabling darker, more visible writing.
Furthermore, the metal refill reduces the pipe thickness, increasing the ink capacity by 70% per pen (※1) and extending the writing distance by approximately 40% (※2), making the ink last longer than before.

② Tip Hold System
Equipped with a newly developed "Tip Holder" that firmly grips the pen tip with a special three-pronged part, reducing wobble and supporting stable writing for better concentration.
③ Noise-Cut Knock
Features a quieter knock with internal springs that absorb impact during clicking. Compared to previous models (※), noise during clicking is reduced by 78% (※ Friction Ball Knock comparison).
Friction is an erasable writing instrument. Do not use on certificates, addresses, or other items that must not be erased.
