The Pilot FriXion Ball Knock Zone, a next-generation erasable ballpoint pen designed for "darker and longer" writing. It features the new "Premium Frixion Ink", which is 30% darker for black and 15% darker for red and blue, housed in a metal refill that increases ink capacity by 70% and extends writing distance by 40% compared to current Frixion Ball refills. The pen also includes a "chip holder" to securely grip the pen tip, reducing wobbling for stable writing, and a "Noise Cut Knock" system with an internal spring to reduce knock sound by 78%.
