- • Best for: Students, planners and illustrators who need consistent, reliable refills
- • Not ideal for: Users requiring non-standard lead diameters or specialty leads
Hi‑polymer leads in standard diameters deliver dark marks and strong break resistance. Supplied in multi-tube packs compatible with most automatic pencils.
Fewer Interrupted Notes – Thanks to an extra-strong, slow-wear core
Hi‑polymer composition and a slow wear rate create a tougher core that resists snapping under typical writing pressure. Break resistance is specifically noted in the product description as a key attribute.
Leads survive heavier strokes and everyday use, so fewer replacements are needed during note-taking or sketching.
Consistent, Dark Lines – With a dense HB graphite formulation
The HB shade produces a darker mark while the slow-wear formula maintains line thickness for longer before needing replacement.
Lines remain legible and even across pages, making them suitable for planners, schoolwork and quick sketches.
