Lead Refills for Mechanical Pencils

These 0.9 mm HB lead refills fit automatic and mechanical pencils that accept the same diameter. The pack contains 15 black leads, each 60 mm long, suited for students and professionals who write or draw daily.

15 Leaves Room for Extended Use

Fifteen leads give weeks of typical writing before a new tube is needed. The HB grade matches a No. 2 pencil for darkness and is guaranteed to scan on standardized tests. Heavy sketching or constant drafting will consume the supply faster than light note-taking.

Tube Format Keeps Leads Organised

The rigid tube protects the 0.9 mm sticks from snapping inside a bag or desk drawer. Proprietary Hi-Polymer formulation reduces breakage during use and delivers a smooth, dark line. No special pencil brand is required beyond compatibility with 0.9 mm lead.

Questions about this item

Will the 0.9 mm HB leads fit my older 0.9 mm mechanical pencil?

Yes, the 0.9 mm diameter matches standard 0.9 mm mechanical pencils so they will feed and advance correctly.

How can I confirm the leads scan properly on a test sheet?

Fill in a sample answer bubble and run it through the scanner; the HB grade is guaranteed to read as a No. 2 pencil mark.

Does the pack include a pencil or just the 15 leads in the tube?

Only the 15 HB leads in a tube are included; a compatible 0.9 mm mechanical pencil must be purchased separately.
