These graphite pencils of a very high (artists / professional) quality, are produced by the renowned family business Koh-i-Noor Hartdmuth. This Czech company has been the worldwide leader of high quality products such as crayons, oil paint, charcoal, chalk, etc., for 225 years. They specialize in many levels of hardness?s. The hardness codes have been devised by the German Friedrich von Hardtmuth of this same Koh-I-Noor factory. He had thought that the H stands for hard (Hart in German), the B soft (Blei in German) and F (this is the current HB) for fine writing (Fein in German).
We offer you these pencils in the range of 4B (very soft) to 4H (very hard), so you can draw whatever you like, draw lines, sketches, shades etc. With a 4H pencil, you may sign or draw on stone and metal material. The soft pencils give you the possibility to create the volatility of charcoal and you can make shadows and depths. The colouring of large surfaces is done with a soft pencil. With the hard pencils you can make very detailed work with sharp turns and glossy lines. A hard pencil is harder to erase then a soft pencil. The pencils HB and H are most suitable for writing.
