Koh-I-Noor produced the first pencil leads by using a mixture of graphite and clay.
Koh-I-Noor’s high quality Yellow graphite pencils glide smoothly over the paper. These pencils have high opacity and are lightfast along with clean erasing qualities. Koh-I-Noor uses high-grade fireproof ceramic clay and graphite, encased in California Cedar to help prevent breakage, especially when sharpening. Koh-I-Noor’s golden yellow artist pencil has been on the market since decades during which period it has won many awards around the world for its impressive quality.
Koh-I-Noor Yellow Artist Pencils come in 20 Grades from 10H (Extra Hard) to 8B (Extra Soft). The softness and darkness of the pencil is determined by the proportion of graphite to clay. Softer grades are best suited for sketching, illustrating and blending as they produce broader and darker strokes, whereas harder grades excel at holding sharp points and are best suited for lithography, technical drafting, architecture and detail work. The HB pencil is ideal for writing and drawing at school.
Koh-I-Noor Yellow Pencils have a 2 - 2.5 mm tick lead. The pencil itself is hexagonal in shape and is 7 mm thick. The pencils are pre-sharpened. Made by Koh-I-Noor in the Czech Republic (Europe), these pencils are similar to Staedtler Lumograph, Sanford Turquoise and Berol Turquoise Pencils.
