0.5 mm HB lead refills, 36-count box

Pentel Super Hi-Polymer leads deliver a fine 0.5 mm graphite point graded HB. The patented formulation reduces breakage and smudging during daily writing. Each box contains 36 refills compatible with standard mechanical pencils. They scan reliably on standardised test sheets.

Consistent density under continuous writing

The Super Hi-Polymer core maintains even laydown across long sessions without crumbling. Extra-strong construction resists snapping when pressure increases. Minimal smudging keeps pages clean during extended use. Performance stays steady from the first stroke to the last refill.

Replaces standard HB refills that snap or smear

Writers who lose points to breakage or smudged scans gain reliability here. The 36-count pack suits high-volume users who refill often. Buyers needing softer or harder grades, larger diameters, or colour leads will not find them in this box.

Questions about this item

Do these 0.5 mm leads produce much dust or smudging during long writing sessions?

The patented Super Hi-Polymer process is designed for minimal breakage and less smudging, so dust stays low even after hours of use.

Will the 36-count box fit my existing mechanical pencil, or do I need a specific brand?

They are compatible with standard mechanical pencils that accept 0.5 mm HB refills, so most models you already own will work.

Can I mix these HB 0.5 mm refills with older leads already in my pencil without jamming?

Yes, the consistent 0.50 mm diameter and HB grade match common legacy leads, allowing smooth mixing in the same pencil.
