Features of Friction Ball Replacement Refills Friction Ballpoint Pen Features [Feature 1] Ink becomes transparent with temperature changes! This innovative ballpoint pen is equipped with "Friction Ink," which turns colorless due to temperature changes. The "Friction Ink" has a set color removal temperature, allowing the ink to become colorless through the friction heat generated by rubbing the special rubber at the back of the body, enabling you to erase your writing. [Feature 2] No eraser residue. Minimal leftover marks. Unlike writing instruments that use erasers, this pen uses friction heat to make the ink colorless, resulting in no eraser residue. Additionally, it leaves significantly less residue compared to pencil or mechanical pencil erasures. [Feature 3] Can be written over and erased repeatedly. Unlike chemical erasers, you can write repeatedly on the erased areas. [Usage] After the ink dries, rubbing with the rubber at the back of the barrel will erase the color. *Not suitable for certificates or addressing. Feature "ZONE TECHNOLOGY" The "Friction Ball Knock Zone" is a next-generation erasable ballpoint pen that responds to user demands for bolder lines and increased ink capacity, allowing for "darker and longer" writing. "ZONE TECHNOLOGY" Feature Introduction ① Version 2 Refill Equipped (Uses "Premium Friction Ink") In response to user requests for bolder lines and increased ink capacity, this metal refill uses newly developed "Premium Friction Ink," which increases ink density by 30% for black and 15% for red and blue compared to the conventional "Friction Ink." This allows for writing that is darker and more visible. Additionally, by using a metal refill and reducing the thickness of the pipe, the ink capacity per refill is increased by 70% compared to conventional resin refills, resulting in approximately a 40% increase in writing distance, allowing the ink to last longer. ② Chip Hold System Equipped with a newly developed "Chip Holder" at the pen tip. This special three-pronged part securely grips the pen tip in accordance with its extension, reducing tip wobble and supporting stable writing for better concentration. ③ Noise Cut An added spring in the internal parts of the knock softens the impact during knocking, resulting in a quieter knock sound. Compared to conventional products, it reduces the knocking sound by 78%. Friction is an erasable writing instrument. Do not use it for documents or addresses that should not be erased.
