This is a newly developed mechanism that focuses on the tip of the mechanical pencil for the first time. The inside of the mechanism is divided into three gears, and the middle gear connected to the core moves up and down using the writing pressure when writing letters. By engaging diagonally with the upper and lower gears, the middle gear and core rotate little by little each time you write a stroke.
