H leads are extremely smudge-resistant and give cleaner lines, making them useful for things such as outlines, technical drawings, light sketches, and even watercolors. With their HB lead and eraser tip, these 3 graphite pencils are perfect for everyday use, in the office, at home or at school.

In 1794, Nicholas-Jaques Conté and Joseph Hardtmuth independently discovered almost at the same time that by mixing graphite with clay it was possible to produce leads with different degrees of hardness, which would preserve the graphite deposits and also accommodate a variety of applications. Likewise, a pencil maker might use the letter “B” to designate the blackness of the pencil’s mark, indicating a softer lead. We address these cases on a case-by-case basis but will try our best to work towards a satisfactory solution.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. The special lead formulation of our artists pencils provides results with a metallic lustre in a wide variety of grey tones for expressive sketches and drawings. Thanks to WOPEX technology, these products can be produced in a more environmentally friendly and resource-conserving way. Thanks to their super-bonded lead, our pencils guarantee high break-resistance and are therefore ideal for use at school and in the office.
