Mars Micro Carbon leads 0.3mm HB - ultra-fine mechanical pencil refill for precision work

The Staedtler Mars Micro Carbon 250 03-HB is a tube of 0.3mm HB mechanical pencil leads in the Mars Micro Carbon formulation, providing the ultra-fine lead refill for mechanical pencils that use 0.3mm diameter leads - the finest standard mechanical pencil lead width used in technical drawing and precision work.

0.3mm is the finest standard mechanical pencil lead width - it produces the narrowest, most precise graphite line available in a mechanical pencil, ideal for very fine technical drawing, intricate detail work and any mechanical pencil user who wants the sharpest, most precise mark. The Mars Micro Carbon formula improves on standard graphite with enhanced smoothness and break resistance - particularly important at the 0.3mm diameter where lead breakage is more likely than at wider gauges. HB grade for the standard mark weight.

  • Ultra-fine 0.3mm carbon lead delivers exceptional precision for technical drawing and engineering drafts.
  • Enhanced break resistance at 0.3mm reduces tip snapping during fine line work and intricate detail.
  • HB grade provides a reliable medium tone for clear, consistent 0.3mm line work.
  • Carbon-infused lead formula ensures smooth, consistent line quality throughout each lead.
  • Tube of 12 leads provides an extended supply for professional and student drawing use.
  • Technical and engineering drawing where 0.3mm lead produces the finest standard drafting line weight.
  • Architecture and design work where maximum precision and detail are critical.
  • TAFE and university technical drawing programmes supplying 0.3mm HB leads to students.
  • General fine writing in 0.3mm mechanical pencils where a quality carbon lead is preferred.
  • Studios and offices maintaining a supply of Staedtler Mars Micro 0.3mm HB leads for ongoing use.
