Pentel PENC5052B 0.5mm 2B Lead Refills 12 Per Tube

Product Description

The PENTEL PENC5052B Super Hi-Polymer lead refills are a 0.5 millimeter, 2B hardness mechanical pencil lead designed for consistent dark lines and smooth writing texture. Each tube contains 12 lead pieces, and the high-density polymer formula delivers writing capacity comparable to a full wooden pencil per piece. These refills are engineered for durability, resisting breakage during normal writing and drafting tasks. The combination of 2B softness and fine 0.5 millimeter diameter makes them well suited to detailed linework, note-taking, and technical drawing where line quality and consistency matter.

These lead refills are intended for use in standard 0.5 millimeter mechanical pencils used in office, school, and technical drafting environments. They fit the writing needs of professionals and students alike who rely on mechanical pencils for precision work. The 2B grade produces a darker, softer line than HB or H grades, making them a common choice for sketching, layout work, and freehand drafting. Sold by the dozen, each order includes 12 individual tubes of 12 pieces each, totaling 144 lead pieces per dozen.

Installation Notes

Handle refills carefully to avoid breakage, as 2B grade leads are softer than harder grades. No tools or trade certifications are required for loading mechanical pencil lead.
