Pentel PENC257BPHB6 Hb Lead Refill 0.5mm 0.7mm 180pc Pack 6

Product Description

The PENTEL PENC257BPHB6 is a multipack of Super Hi-Polymer HB lead refills for mechanical pencils, combining both 0.5mm and 0.7mm sizes in a single value pack. Using a proprietary polymer formula, the lead delivers crisp, consistent dark lines with smooth density across both diameters. The break-resistant composition reduces waste during heavy use, making it a practical choice for office staff, students, and field technicians who rely on consistent legible marks. Each pack contains 180 individual pieces total across both sizes. Meets No. 2 lead standards for accurate results on optically scanned forms and standardized test sheets.

These lead refills are suited for general writing, note-taking, faxing, photocopying, and electronic document scanning in office, classroom, and light field environments. The HB grade produces a balanced line weight that reads clearly on standard white and colored stock. Both the 0.5mm and 0.7mm sizes fit most standard mechanical pencils that accept those respective bore diameters. The 180-piece total across the Pack of 6 provides a reliable bulk supply for high-turnover settings such as testing centers, office supply rooms, and educational facilities.

Installation Notes

Lead refills are loaded by office personnel or end users according to the mechanical pencil manufacturer's loading procedure. Retract or remove the existing lead tip before inserting new pieces to avoid jamming the advance mechanism. Handle individual leads carefully to avoid contact breakage prior to use. No tools or trade credentials are required for standard refill loading.
