Pentel Ain Pencil Lead Refill 0.5mm HB, 40 Leads per Tube, Break-Resistant Graphite for Mechanical Pencils, Smooth & Dark Writing - 40 Leads/Tube - Pack of 2 Tube

The refill is 0.5mm HB graphite, engineered for break resistance and smooth writing. Each tube contains 40 leads, and the product comes as a pack of 2 tubes.

You get 2 tubes with 40 leads each, totaling 80 leads. Exact longevity depends on your writing or drawing habits, but having two tubes ensures a long-lasting supply for school, office, or studio use.

This lead refill fits most standard 0.5mm mechanical pencils, making it a versatile option for a wide range of devices.

Step 1: Remove any old lead. Step 2: Insert a fresh 0.5mm HB lead into the pencil’s lead tube. Step 3: Gently advance the lead until it protrudes slightly from the tip. Step 4: Test by pressing lightly on paper to ensure smooth feeding and writing.

If leads break frequently, try using a pre-feel test line to ensure you’re not applying excessive pressure. Check that the pencil’s mechanism is clean and that the lead diameter matches the pencil’s internal guide. Writing with a lighter touch and a consistent speed can also reduce breakage.

The HB grade delivers smooth, dark lines with a balanced tone. The break-resistant formulation helps maintain continuous lines during writing, sketching, or technical drawing, while still offering clean erasing on most papers.

Ideal for students, professionals, and artists who need reliable, smooth-writing leads for note-taking, drafting, technical diagrams, and shaded sketches in 0.5mm mechanical pencils.

Keep the tubes in a cool, dry place with the cap securely closed. The compact, mess-free dispenser helps prevent spills and keeps leads from bending or breaking when not in use.

Yes. Graphite lead refills are non-toxic and designed for everyday writing, sketching, and drawing. As with all stationery products, keep away from small children who might accidentally ingest small parts.

This Pentel Ain 0.5mm HB refill emphasizes break resistance and clean erasing with a smooth writing feel.
