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

HB is considered a middle-ground grade, offering a comfortable balance between darkness and erasure. It’s darker than F and lighter than B, making it well-suited for clear notes and clean lines without excessive smudging.

The lead uses a break-resistant formula designed to withstand typical pressure during writing and light drafting. This reduces frequent lead snapping when you press firmly or when the pencil tips encounters resistance.

Yes, it’s designed to fit most standard 0.5mm mechanical pencils. If your pencil uses a standard 0.5mm lead, it should work with these refills.

Each tube contains 40 leads, providing a substantial supply for regular writing, note-taking, or drawing over weeks to months depending on usage.

Remove any remaining old lead, insert a fresh 0.5mm Ain lead into the pencil’s lead sleeve, and gently advance it until it extends about 1–2 mm from the writing tip. Start writing and feed the lead as needed.

Students use it for notes and exams; professionals may rely on it for precise drafting and technical writing; artists can use it for smooth shading and clean lines in sketches.

HB graphite typically erases cleanly with a standard eraser on most papers. For best results, use a quality eraser and avoid heavy layering of graphite in one spot.

Graphite leads are generally non-toxic and safe for regular use. Keep the product out of reach of small children due to small parts and choking hazards, and dispose of the packaging according to local recycling guidelines.
