Pentel Ain-Stein Slim Mechanical Pencil Leads, 0.7 mm, HB, Break-Resistant Core, Clean Erasing, Smooth Writing, Ideal for Everyday Task – Pack of 5

The 0.7 mm line provides fuller strokes that improve visibility on copies, forms, and other documents, making your writing easier to read at a glance.

The Slim tube is a compact case that holds the five leads and makes refills easy to dispense, helping keep pencil pouches and desks neat and organized.

The HB core is designed to be tough enough to resist breaking during quick, casual note-taking, reducing interruptions while you write.

Yes, these HB leads erase cleanly, helping you correct mistakes without leaving heavy or smudged marks on your pages.

They’re great for daily writing at home, in class, or in the office, as well as for filling out forms, doing problem sets, planners, and other everyday tasks.

Open the pencil’s lead-advance mechanism, drop a lead into the chamber, or replace the refill cartridge if your pencil uses one, then test by gently advancing the lead until it writes smoothly.

They are designed for 0.7 mm mechanical pencils. If your pencil uses a standard 0.7 mm refill system, these leads should work; always verify your pencil’s refill type before use.

They are standard graphite leads intended for regular writing tasks in school and work settings. As with any small item, keep them away from very young children to avoid choking hazards.

Compared with other 0.7 mm HB leads, Ain-Stein Slim emphasizes a darker line, slimmer refill packaging for easier storage, and a tougher HB core to reduce breakage during rapid writing. For direct comparisons, you can explore similar 0.7 mm HB refill options from Pentel or other brands on Fepy’s site.

The pack includes 5 leads, offering a convenient, cost-effective option for regular use without frequent reorders.
