About the Staedtler Mars Micro Carbon Lead

The Staedtler Mars Micro Carbon series represents the pinnacle of German lead engineering. While many modern leads rely on synthetic binders, Staedtler utilizes a high-purity natural graphite blend (over 90%) to ensure every stroke is exceptionally smooth and deep in color. This high carbon content provides superior opacity, making your work easier to scan and highly resistant to smudging.

Advanced Engineering & Compatibility:

• Flexible Durability: The carbon structure is designed to be ultra-flexible, allowing the lead to bend slightly under pressure rather than shattering, which is crucial for fast sketching.
• No-Touch Refilling: Signature Staedtler tubes are specifically designed to fit into the barrel of Staedtler Mars Micro and 925 series pencils, allowing for a seamless reload experience.
• Specialized Red Graphite (Available for Selection): The rare 254 series 0.5mm Red lead is available as a specific variant, formulated for professional non-photo marking, correcting, and sketching. Engineered for high erasability, it allows for clean revisions without ghosting.
