If you use a 2mm mechanical pencil for drafting, sketching, or technical drawing, you know how important good lead is.

This Koh-I-Noor refill pack gives you two tubes: one with 12 leads in 2B hardness, and another with 12 leads in 4B hardness.

That's 24 leads total, which should keep you going for a while.

The 2mm diameter is standard for many clutch-style drafting pencils, and the graphite quality is smooth and consistent – perfect for precise lines or shading.

Whether you're an architect, artist, engineer, or student, having both 2B (medium-soft) and 4B (softer) gives you flexibility for different effects.

Just pop out the old lead, slide these in, and you're back to drawing.

Reliable, professional-grade refills from a trusted brand in drawing supplies.
