These instruments of writing are also known as the ''Four Friends of the Study'' ({{langx|ko|문방사우/文房四友|Munbang sau}}) in Korea. Besides the traditional four tools, [[desk pad]]s and paperweights are also used.

Many different parameters influence the final result of a calligrapher's work. Physical parameters include the shape, size, stretch, and [[Brush#Bristles|hair type]] of the ink brush; the color, color density and water density of the ink; as well as the paper's water absorption speed and surface texture. The calligrapher's technique also influences the result, as the look of finished characters are influenced by the quantity of ink and water the calligrapher lets the brush absorb and by the pressure, inclination, and direction of the brush. Changing these variables produces thinner or bolder strokes, and smooth or toothed borders. Eventually, the speed, accelerations and decelerations of a skilled calligrapher's movements aim to give "spirit" to the characters, greatly influencing their final shapes.
