Pentel Ain-Stein Slim Mechanical Pencil Leads, 0.7 mm, HB, Break-Resistant Core, Bold Stroke, Clean Erasing, Smooth Writing, Ideal for Everyday Task

The HB core is engineered to resist tip breakage during regular writing and erasing tasks. This helps you avoid interruptions when taking notes, drawing diagrams, or writing quickly, making it reliable for everyday use.

Remove the pencil’s eraser cap (or access point), insert a 0.7 mm lead into the lead sleeve, and gently push the pencil’s plunger or feeder until the lead advances. Repeat as needed while writing.

Yes. The 0.7 mm HB leads deliver darker, readable lines ideal for notes, diagrams, and casual sketches, with smooth writing and clean erasing.

These leads are designed to erase cleanly without heavy smearing, making corrections neat on most standard erasers and paper types.

They are compatible with most standard 0.7 mm mechanical pencils. If your pencil accepts standard 0.7 mm leads, they should fit and feed smoothly.

The Slim design emphasizes portability and ease of use in tight spaces, while the compact tube makes it convenient to carry refills in a pencil case, pocket, or bag.

The product is packaged as a refill lead set in a travel-friendly tube suitable for on-the-go use. Exact counts can vary by packaging batch, but the tube is designed to supply multiple writing sessions between refills.

0.7 mm HB provides a bolder, more legible line, which is helpful for notes and diagrams. A 0.5 mm lead produces finer lines with crisper detail, better for precise work. Choose based on how bold you want the lines and the level of detail you need.

Graphite leads are generally non-toxic and safe for everyday use. Avoid ingestion and keep away from small children and pets, as with any small writing accessory.
