Ideal Use

Safety and Maintenance

• Loading Tip: To avoid wastage, only load two or three leads at a time into your pencil to prevent jamming or internal breakage.
• Storage: Keep the dispenser closed when not in use; the rigid plastic case is designed to protect the brittle leads from snapping during transport in a pencil case.
• Handling: Avoid touching the lead directly with oily fingers, as this can occasionally affect the smoothness of the graphite on the paper.

Frequently Asked Questions

• Are these leads easy to erase? Yes, the high-quality graphite is designed to be lifted easily by standard PVC-free erasers without leaving ghosting marks.
• Will these fit any mechanical pencil? They are compatible with any brand of mechanical pencil as long as the pencil is designated for 0.5mm leads.
• Why choose HB over other grades? HB is the most versatile grade, suitable for the widest variety of writing and drawing tasks in school and business environments.
• Do they produce a lot of dust? No, the Staedtler formula is designed to be low-residue, keeping your documents and hands clean.

The "Jam-Free" Pro Tip

• If your mechanical pencil feels stuck, don't force the clicker.
• Most 0.5mm pencils can be "cleared" by removing the eraser and inserting a single Staedtler HB Lead from the back.
• If a small piece of lead is stuck in the tip, use one of these fresh refills to gently push the blockage through while holding the clicker down, ensuring your pencil stays in perfect working order for your next business meeting or exam.
