Pentel PENC27HBBX 0.7mm Hb Black Lead Refill 12-box

Product Description

The PENTEL PENC27HBBX is a box of 12 tubes of Super Hi-Polymer mechanical pencil lead refills in 0.7 millimeter diameter and HB hardness. Each tube contains 30 individual lead pieces, giving the box a total of 360 leads. These refills produce consistently dark, smooth lines without excessive smearing or skipping. The super-strong polymer core resists breaking under normal writing pressure, making it a dependable choice for high-volume use. Licensed HVAC techs, estimators, inspectors, and office staff who rely on mechanical pencils for forms, logs, and field sketches will find this refill a straightforward restock item.

This product is suited for general office, drafting, and field documentation environments. The 0.7 mm diameter is a widely used size compatible with most standard mechanical pencils designed for that lead diameter. HB hardness sits at the center of the hardness scale, delivering a balanced combination of dark mark-making and reasonable point retention. The box-of-12 format supports bulk stocking for supply rooms, service fleets, or multi-tech operations that burn through pencil lead regularly.
