Portaminas Noris Staedtler Mars micro 775 — mina 0,9 mm B, unidad individual, negro/azul/naranja

Noris Staedtler Mars micro 775 mechanical pencil with 0.9 mm B lead is a durable writing and drawing instrument designed for technical and everyday use. The single-piece body is available in ISO colour-coded black, blue or orange and features a retractable metal lead sleeve for pocket safety, a metal clip and a push-button feed. The 0.9 mm B lead delivers darker, smoother lines suitable for sketching, note-taking and detailed technical drawing, while cushioned lead mounting reduces breakage. The pencil includes a refillable eraser (PVC- and latex-free) with protective cap and is easy to refill with compatible STAEDTLER Mars micro 250 carbon leads.

Advantages

The non-slip rubber grip zone ensures a secure hold during extended use and the cylindrical metal lead sleeve allows precise work along rulers and templates. A cushioned lead system improves break resistance when working with softer B lead, and the retractable sleeve plus robust metal clip increase pocket safety and durability. The pencil is refillable and compatible with standard 0.9 mm leads, reducing waste and extending service life.

How to use

Advance the 0.9 mm B lead by pressing the push-button; the retractable metal sleeve protects the lead when stored and retracts to allow precise contact while writing or drawing. Hold the pencil by the non-slip rubber grip zone for stable control and use the cylindrical sleeve when drawing along rulers or templates to maintain consistent lines. To replace lead, remove the protective cap from the eraser compartment if required and insert compatible 0.9 mm mechanical pencil leads. The eraser is refillable and can be replaced with the supplied protective cap to prevent damage.

Recommendations

For best results in technical drawing and shading, use a steady hand and moderate pressure; the B lead produces darker strokes, so lighter pressure will preserve detail and reduce smudging. Keep spare 0.9 mm leads on hand and replace the eraser refill when worn. The retractable sleeve makes the pencil suitable for pocket carriage, but always retract before storing to protect the lead and surrounding items.
