To complement our standard drawing pencils, which are characterised by lead with a silvery lustre, the Mars Lumograph black (available in six hardness grades) has a high proportion of carbon and is recommended for matt, jet black results.

You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. With our Noris eco, made from innovative WOPEX material, we have revolutionised the pencil and its manufacturing process.

It is therefore suitable for artists, particularly for drawing and shading, as well as for expressive sketches and portraits. Today, however, most pencils using the HB system are designated by a number such as 2B, 4B or 2H to indicate the degree of hardness.

The Lumograph aquarell is available in three graded consistent degrees of hardness and is therefore particularly suitable for creating a variety of grey and black tones in conjunction with water.

Thanks to its non-slip grip, the Mars ergosoft jumbo pencil is ideal for children’s first writing exercises in primary school. This is why STAEDTLER is certified for the production and sale of wood-cased pencils in accordance with current FSC and PEFC standards (chain of custody/CoC certification). The red and black striped models from our traditional series offer comparable quality to our Noris pencils. Most pencil manufacturers set their own internal standards for graphite hardness grades and overall quality of the core, some differences are regional.Our Noris eco pencils are produced using a newly developed, innovative technology: WOPEX (Wood Pencil Extrusion). Using this scale, the hardness of the core is often marked on the pencil — look for a number (such as “2” “2-1/2” or “3”). We address these cases on a case-by-case basis but will try our best to work towards a satisfactory solution. There is nothing wrong with the pencil itself of course but I think that the photo should make it clear that it’s only one pencil.

As the pencil core becomes softer (through the use of lower proportions of clay) it leaves a darker mark as it deposits more graphite material on the paper. They're perfect for pencil drawings as artists can take advantage of the brush-like expressions, especially in the higher B grades. As you can see in the image, the higher the H value, the lighter the result but the finer the point, while at the other end, the higher the B value, the darker the blackness of the graphite and wider the point.In reality however, there is no specific industry standard for the darkness of the mark to be left within the HB or any other hardness grade scale. Faber-Castell was the first manufacturer to introduce the environmentally-friendly water-based varnish technology, which is used for almost all writing instruments produced at the main factory in Stein.

Our range of pencils also includes the Mars Lumograph aquarell high-quality watercolour artists pencils. The same scale of hardness is used in ISO standards (for example for the determination of film hardness of paints by pencil test; in this test method, calibrated pencils of known hardness are pushed over the film). Like all BIC Evolution pencils, their ultra-strong lead is impact-resistant, easily sharpened and erasable.Additionally make sure your User-Agent is not empty and is something unique and descriptive and try again. WellI'veseenlotspeopleusingpencilsinsteadofpensandgettingUs,soiftheexaminersdidn'tevencaretomarkthosewholepapersmanuallywhywouldtheycareforthis? Well, it all has to do with the HB graphite grading scale used to classify the pencil’s graphite core.
