Lead Refill Staedtler Mars Carbon 200 4H Blue
Staedtler Mars Carbon 200 4H Blue mechanical pencil lead refill delivers precise, hard graphite in a consistent blue tone for detailed writing and technical drawing. Packaged as a set of twelve leads, this refill is designed to fit compatible mechanical pencils that accept standard cartridge leads. The 4H hardness provides light, fine lines with low smudging, making it suitable for drafting, sketching, and note-taking where clarity and clean reproduction are required.
The 4H hardness ensures a firm lead that resists breakage under controlled pressure and produces sharp, crisp lines with minimal graphite dust. The blue coloration offers clear contrast on white or off-white paper while remaining suitable for scanned or photocopied documents. Each lead is manufactured to consistent diameter and density standards, providing reliable feed and uniform stroke quality across multiple uses.
Insert a lead into a compatible mechanical pencil according to the pencil manufacturer's instructions. Advance the lead gently to the desired length and apply light, consistent pressure to maintain the fine quality of lines typical for 4H hardness. Replace the lead when line density decreases or the lead becomes too short for secure clamping. Store unused leads in their original packaging to prevent damage and contamination.
Use on medium- to high-quality paper to minimize tearing and to preserve line sharpness; avoid excessive pressure to reduce the risk of breakage. For drafting work that will be scanned or reproduced, test a sample to confirm the blue tone and line visibility meet reproduction requirements.
