Náhradná tuhá mina Staedtler Mars micro carbon 250 0,7 mm 2B

Lead refill Staedtler Mars micro carbon 250 0.7mm 2B is a mechanical pencil lead designed for writing, sketching and technical drawing. The 0.7 mm thickness and 2B softness deliver smooth, jet-black lines with good balance between fine detail and visible stroke. The carbon-based lead features high break resistance and is compatible with most mechanical pencils, including many STAEDTLER models that allow quick “12-a-go” refilling.

Advantages

The flexible 2B lead resists breakage while providing smooth gliding on paper and drawing card. Manufactured using an ecological process without PVC or softening agents and made from more than 90% natural raw materials, the refill combines durability and environmental consideration. ISO colour coding and tubes containing 12 leads ensure convenient identification and storage.
