Pentel PENC25BPHB3K6 Pencil Lead Refill 0.5 Mm Hb 3-pack

Product Description

The PENTEL PENC25BPHB3K6 is a Super Hi-Polymer mechanical pencil lead refill in 0.5 mm diameter with HB hardness. Each tube contains 12 individual lead pieces and delivers consistent dark, smooth lines suitable for writing, note-taking, and detailed technical drawing. The polymer composite formula is engineered for high break resistance, giving each lead the writing length equivalent to a full wooden pencil. This pack includes three 12-piece tubes for extended on-the-job or desk use. Technicians, drafters, and field professionals who rely on mechanical pencils for documentation and markup work will find this refill a straightforward stock item.

These lead refills are suited for general office, school, and technical field applications where fine line quality and consistent density are required. The 0.5 mm diameter fits standard 0.5 mm mechanical pencils. The HB hardness rating produces a dark, readable line without excessive smearing, making it practical for forms, sketches, and written notes alike. The three-tube pack format reduces restocking frequency for regular mechanical pencil users.
