Pilot Neox Graphite Lead comes in a variety of sizes and densities. Lead density affects how light or dark the line on the page is. A softer lead (such as 'B') leaves more material on the paper creating a dark bold line, whereas a harder lead (such as 'H') leaves less material on the paper and leaves a lighter line.
