Faber-Castell Super Polymer Fineline Lead, HB, 1.0 mm Compatible, Easy to Refill, Bold Stroke, Ideal for Technical Task, Tube of 12 Leads - Pack of 12 Tube

HB indicates a balanced hardness suitable for everyday writing and drawing, while 1.0 mm refers to the lead diameter that fits in standard 1.0 mm mechanical pencils, offering a bold, visible line.

Polymer blend for dark, even lines with low drag and dust, break-resistant formulation to resist snapping under normal pressure, and a clean refill design to minimize spills during top-ups. It’s also compatible with most 1.0 mm mechanical pencils and provides an archival, deep black tone.

This lead is designed for most 1.0 mm mechanical pencils, so it should insert and write smoothly in compatible models without jams.

Use the included clean-refill mechanism and feed the new lead through the top of the pencil gently. Avoid forcing the lead, keep the barrel steady, and cap the tube after use to prevent spills.

Apply moderate, steady pressure rather than heavy pushing, keep the pencil tip in good condition, and use fresh leads from a dry, cool storage. If you experience frequent breaks, switch to a compatible 1.0 mm lead with a tougher formulation.

Ideal for technical tasks like drafting, architectural sketches, diagrams, and precise handwriting where bold, dark lines are beneficial and need clean, crisp reproduction.

Yes. The polymer-style lead is designed for normal handling in educational and professional settings. As with any mechanical pencil refill, avoid ingestion and keep away from small children.
