A linear roller pen, also known as a rollerball pen, is a type of writing instrument that uses a ballpoint mechanism to dispense ink. It combines the smoothness of a fountain pen with the convenience of a ballpoint pen. The ball at the pen's tip rotates as it moves across the paper, allowing the ink to flow out consistently and providing a smoother writing experience compared to traditional ballpoint pens.
