A plain pen refers to a pen without coloring, also called a white pen. In the field of painting, plain pens are usually used to draw outlines and details. Because it does not affect the color, it is convenient for coloring later. In Chinese paintings and comics, plain brushes are often used to draw black and white lines to show the beauty and thickness of the lines in the work.
Simple pens are more widely used in the field of calligraphy. Plain calligraphy refers to using an uncolored pen to write black and white calligraphy and painting on white paper. It focuses on highlighting the lines, structure, and shape of the handwriting. It is also the basis for learning calligraphy. Because plain calligraphy can better highlight strokes, glyphs and attainments, it is very popular among calligraphy enthusiasts and has become an indispensable part of the art of calligraphy.
In addition to the artistic field, plain pens also play an important role in life. In daily office learning, plain pens are often used as a writing tool with a smooth pen barrel and smooth handwriting. It is not as thick as an ink pen, nor is it as dry as a ballpoint pen. The natural and smooth lines can not only increase the writing speed, but also reduce hand fatigue. At the same time, plain pens also have the advantages of preservation, antisepsis, and easy portability, and have become one of the indispensable writing tools in people's daily lives.
