Recarga de minas Staedtler 250 05-HB cinzento 0,5 mm

Staedtler 250 05-HB lead refill contains twelve 0.5 mm grey leads with HB hardness designed for precise writing and drawing on paper and drawing card. The leads glide smoothly and produce jet-black lines while offering high break resistance thanks to a flexible formulation. Manufactured using an ecological process without PVC or softening agents and made from more than 90% natural raw materials, these refills fit most mechanical pencils and include ISO colour coding for easy identification.

Advantages

High break resistance and flexible composition reduce the risk of crumbling during use while maintaining smooth, dark strokes. The ecological manufacturing process avoids PVC and softening agents and uses predominantly natural raw materials. Compatible with a wide range of mechanical pencils and supplied in convenient 12-lead tubes with simple refilling for many STAEDTLER models.

Recommendations
