pen · 模型 46477
A pen is a writing device that uses ink to write on the surface of paper or other media. A pen usually consists of a plastic or metal tube containing liquid ink, with a small ball-shaped tip that serves to drain the ink when pressed onto the writing surface. Pens are very popular for their practicality, as well as their availability in a variety of ink colors, designs, and types, ranging from ballpoint pens, gels, to rollerballs. A pen is often used in everyday life to write notes, sign documents, or draw.
