滚珠笔, 圆珠笔
a pen that uses a small rotating ball made of steel, carbide, or ceramic to dispense ink as it moves across a writing surface
A rollerball pen is a type of pen that uses water-based ink, which flows smoothly and consistently from a rolling ball at the tip of the pen. The ball, usually made of steel, rotates as the pen moves across the paper, distributing the ink evenly and creating a smooth writing experience. Rollerball pens are known for their rich, vibrant colors and fine lines. They are often preferred for their smoothness and precision compared to ballpoint pens, making them a popular choice for writing, drawing, or signing important documents.
