Náhradná náplň Staedtler Mars micro carbon 250 0,5 mm 2B

Staedtler Mars micro carbon 250 0.5mm 2B lead refill provides 0.5 mm 2B leads designed for smooth writing and precise drawing on paper and drawing card. The flexible, high break-resistance carbon leads produce jet-black lines and are manufactured using an ecological process without PVC or softening agents, with more than 90% natural raw materials. Each transparent tube contains 12 leads and the product follows ISO colour coding; it fits all mechanical pencils and offers a simple “12-at-once” refilling for many Staedtler mechanical pencils.

Advantages

Flexible leads with high break resistance reduce interruptions during writing or sketching while delivering consistently dark, smooth-gliding lines. The ecological production method avoids PVC and softening agents and uses predominantly natural raw materials. Compatibility with standard mechanical pencils and the convenient 12-lead tube make refilling quick and easy.

How to use

Open the tube and insert a single lead into the tip of a compatible 0.5 mm mechanical pencil according to the pencil manufacturer’s instructions. Advance the lead gradually while writing or drawing; replace with a new lead from the tube when the previous one is used up. For models with “12-at-once” refilling, follow the pencil’s refilling procedure to load the full tube if supported.

Recommendations

Store leads in the original tube to protect them from breakage and moisture. Use the 2B hardness for darker, softer lines and consider a harder grade for finer, lighter technical lines.
