3 - 12 HB each (total of 36). 02199 (2375) Sanford Turquoise Prismacolor Lead 2mm lead has a perfectly graded hardness that's produced from a mixture of crystalline graphite and super-refined clay. They are designed to fit most lead holders and clutch style pencils. Lead hardness is determined by the clay to graphite ratio; harder drafting lead has a higher percentage of clay than softer sketching leads. The Conté system shop is a popular scale for rating pencil hardness, with 9H measuring the hardest through 9B the softest. The 2mm Sanford Prismacolor drawing leads are popular for sketching and material applications. Check pictures. All in New condition. Check my other listings for more drawing leads.
