Sell *callipatty* Berkeley Drawing Pencils best price

Berkeley Drawing Pencils is a budget-friendly graphic pencil for students. Pencil manufacturers began to mix graphite with clay, controlling the hardness and softness of pencils by adjusting the ratio of the softer graphite to the harder clay filler. A hard pencil contains more clay filler, resulting in tightly packed graphite that leaves a light mark on your paper. On the other hand, a soft pencil contains more graphite and less clay filler, leaving a darker mark on your paper. Graphite drawing pencils are graded on the HB scale, where H signifies “hard” and B signifies “black.” An HB pencil is directly in the center of the scale, whereas a 9B pencil, for example, is extremely soft and leaves a black mark. Conversely, a 9H pencil is exceptionally hard and leaves a light, gray mark. Grades available: HB B 2B 3B 4B 5B 6B #berkeley #pencils #drawing
